Reviews of Top Proof of Work Coins to Invest in 

We researched 9 of the best proof of work coins, and our detailed reviews and analysis of each including how they may benefit investors can be found below.

1. RobotEra - Best Alternative to PoW Cryptos with Metaverse & NFT Features

While projects like The Sandbox have captured the imagination of crypto enthusiasts around the globe, many lack substance. However, RobotEra (TARO), is aiming to develop a more detailed metaverse world that provides players with far more opportunities. TARO, RobotEra's native token has recently entered presale, meaning it's a great time to get involved.

The Ethereum-based TARO token is used to power the RobotEra ecosystem, meaning that it needs to be able to facilitate high-volume, low-cost transactions. Therefore, rather than opting to utilize the proof-of-work consensus mechanism, RobotEra opted to utilize proof-of-stake which boasts lower costs and far more efficient transaction settlements.

While TARO is one of the best proof-of-stake coins to invest in right now, it's got more utility than simply being an investment vehicle. The TARO token acts as a form of governance, meaning that holders can pledge tokens to gain voting rights. This should ensure that any update to the project always has the community's best interests at heart.

If you're curious about RobotEra and wish to learn more about the project, the below video from YouTuber Jacob Crypto Bury details the ins and outs of the project. 

In one of the best opportunities within the crypto space right now, TARO is available as a presale with the price of the token starting at just $0.020. While this could be an excellent deal for such a utility-heavy token, the price of TARO will slowly rise, hitting $0.025 during the second and $0.032 during the third presale stages.

With only 270 million of TARO's 1.8 billion token supply being reserved for presale investors, it's likely that each stage will sell out quickly, meaning it could be a good idea to check out the project early to avoid disappointment. Read through the RobotEra whitepaper to learn more about the project.

Players in the TARO metaverse can explore a vast world comprised of seven NFT-based continents. On these virtual land masses, players can use the creator tools to build impressive structures that can be utilized for concerts, office space, and more. Furthermore, RobotEra's building tools have been built from the ground up for ease of use, meaning no coding is required.

Further adding to RobotEra's utility, players can find resources while exploring that can be mined and used to construct robot companions that can be sold on the in-built NFT marketplace. Just about every in-game asset takes the form of an NFT, meaning that most items are unique and can be easily traded, helping to promote a strong economy. 

All in all, while RobotEra doesn't utilize the proof-of-work architecture, it's an excellent proof-of-stake alternative that offers equal if not greater room for growth. With TARO currently being available for the lowest presale price, there's no better time to check out RobotEra. Join the RobotEra Telegram group now to keep up-to-date with any developments.

2. Tamadoge (TAMA) - Proof Of Work Crypto Meme Coin with P2E Elements

Tamadoge is a new meme coin offering high utility and rewards. This P2E game enables players to compete for crypto rewards by looking after virtual pets. Players who nurture their pets into adulthood the best climb the leaderboard to collect free crypto.

As well as rewarding players with TAMA tokens the Tamadoge platform has a multi-year roadmap to offer a better crypto gaming experience and more opportunities to earn. Two of the developments upcoming in 2023 are a Tamadoge P2E Arcade game, offering physical Tamadoge rewards and token prizes, and the augmented reality app — making player/pet interaction more realistic.

The other development is the token burn. TAMA tokens are already limited to a fixed maximum supply of 2 billion, and the game's developers will burn 5% of all tokens received from transaction fees in the pet store purchases. 

That will decrease the coin's supply over time, and the increased exposure after its exchange listing on OKX will raise demand, making it one of the best cryptos to buy and hold for the long term.

TAMA's exchange listings have become convenient thanks to its ERC-20 token and proof of work mechanism that will be used for verifying its transactions once the presale ends. Tamadoge already had one of the best crypto presales of 2022, selling $19 million of tokens in just eight weeks.

Investors can stay up to date with the coin's latest developments by subscribing to the Tamadoge Telegram channel. Bear in mind that the channel's admins never DM subscribers first, so watch out for imposters.



3. Battle Infinity (IBAT) -  Popular Metaverse P2E Gaming Platform

Battle Infinity has become one of the most popular P2E Metaverse games, enabling players to receive rewards from six platforms. Players can buy the native token, IBAT, on Battle Swap, a decentralized exchange on the platform, to build up teams and compete in the IBAT Premier League.

The game enables players to buy NFTs in Battle Marketplace to use as fashion accessories on their avatars. Players can also stylize their characters with unique hairstyles and use them to explore the Metaverse in Battle Arena while interacting with players in real time.

One of the ways players earn IBAT tokens is by monetizing their land. Another way is by staking their coins. Players can choose solo, duo and crates staking. Battle Infinity also rewards the most active players from the global staking pool, which receives half of the transaction fees on the platform.

IBAT's presale was scheduled to last 90 days, but high demand for the coin resulted in it selling out within 25 days. During the presale, IBAT was available for $0.0015. The coin's popularity was evident in the exchange listing, as IBAT's price surged 700%, proving it's one of the fastest growing cryptocurrency to invest in

The game's developers wanted to facilitate efficient and low-cost transactions, so they developed a BEP-20 token. Although Battle Infinity uses a proof of stake consensus mechanism, its platform offers investors several ways to earn rewards and potentially profit from price pumps when listed on new exchanges. 

Investors can stay informed about Battle Infinity's developments by joining the Telegram channel.

4. Lucky Block (LBLOCK) - Top-Rated NFT Competition Platform

One of the most popular proof of work cryptos is LBLOCK. Initially, the project created a BEP-20 token enabling investors to earn rewards but also incur sales tax. Lucky Block developed LBLOCK V2, an ERC-20 token containing no sales tax and enabling centralized exchange listings.

Major exchanges LBank and MEXC have listed LBLOCK. The most recent listing was Gate.io on 1 September 2022. This coin's history proved that its price pumps during new listings. Lucky Block CEO Scott Ryder announced that more exchanges will also list the coin.

Another key announcement was the token burn. To make the coin more valuable, Ryder stated a 1% monthly token burn will commence on 30 September 2022. Lucky Block has partnered with exciting Web3.0 projects, which it will announce soon.

Besides the potential capital appreciation, Lucky Block enables investors to enter prize draws. Investors enter the draws by owning LBLOCK and accessing the Platinum Rollers Club NFT to stand a chance of winning a Lamborghini, $1 million in Bitcoin and a house worth $1 million. Transaction fees don't apply to buying coins for draws.

Lucky Block started as a prize-giveaway platform offering exotic vacations and has progressed to an NFT competition platform giving away major prizes and offering two tokens, proving it's one of the best long term crypto projects.

5. Litecoin (LTC) -  Bitcoin Fork Offering Near-Instant Transfers

Litecoin is one of the oldest cryptocurrencies, released in 2011 by its creator, Charlie Lee. The platform developed as a Bitcoin fork after Lee noticed that Bitcoin's transactions were hefty and slow.

That resulted in the development of a Bitcoin alternative, an open source, global payment network that provides instant, near-zero cost payments globally. Litecoin's network handles a higher transaction volume than Bitcoin because of more frequent block generation.

Litecoin is software that enables users to run, modify, copy and distribute it. The platform's use of proof of work means anyone with sufficient hardware can add blocks to its blockchain. Individuals verifying transactions are referred to as miners, who are rewarded 12.5 LTC per block.

Its halving occurs every 840,000 blocks (approximately every 4 years), resulting in the network producing 84 million LTCs. 

Since the crypto community deems Litecoin as a Bitcoin alternative, it's potentially one of the best altcoins to buy.

6. Bitcoin Cash (BCH) - Efficient and Affordable Bitcoin Alternative Platform

Bitcoin Cash is also a fork of Bitcoin and dubbed the Bitcoin 'Peer to Peer Electronic Cash'. While Bitcoin is regarded as gold 2.0 and a store of value, Bitcoin Cash would be a credit card used for everyday transacting.

The Bitcoin fork increased the size of the blocks, enabling Bitcoin Cash to handle a larger volume of transactions and improve scalability. 

Much like Litecoin, Bitcoin Cash was developed to offer faster and cheaper transactions. Its network operates without congestion, and transactions are confirmed within minutes. It costs mere pennies to send BCH globally and offers several levels of privacy.

Bitcoin Cash uses the proof of work algorithm to timestamp new blocks. The project used the same mining algorithm as Bitcoin, known as Emergency Difficulty Adjustment (EDA) — adjusting difficulty every 2016 blocks.

The platform has revised its EDA algorithm to make it more convenient for miners to earn BCH.

7. Ethereum Classic (ETC) - Ethereum Fork Running Smart Contracts and Apps 

The hard fork of Ethereum's network resulted in the separation of two blockchains and the formation of Ethereum Classic. ETC's technology differs from Ethereum's and is capable of running a wide variety of applications.

ETC powers transactions and smart contracts on its platform and is also rewarded to miners for solving proof of work puzzles by verifying transactions. Unlike Ethereum, Ethereum Classic is committed to using proof of work indefinitely.

The project insists that proof of work is the true consensus mechanism, providing censorship resistance. Ethereum Classic developers also believe that projects migrating to proof of stake are financially motivated and don't do it because of environmental concerns.

Ethereum Classic acknowledges that proof of work isn't a perfect system and is subject to 51% attacks. But its chains have functioned resiliently for over 10 years and prioritize critical qualities providing blockchain utility.

8. Bitcoin (BTC) - Highest Market-Cap Crypto and Original Proof of Work Coin

Bitcoin's epic rallies have made it one of the top trending cryptos. It's the first coin to take off in a bull run and pave the way for altcoins. BTC is the most popular crypto and has the largest market cap in the digital asset market.

Bitcoin is the first crypto developed to use the proof of work consensus mechanism. The effectiveness of Bitcoin's use of proof work hasn't deteriorated throughout the years, regardless of the BTC price. But it requires special hardware and relies on microprocessors. 

By using proof of work since 2009, Bitcoin has provided a borderless, decentralized currency enabling peer-to-peer transactions at any time. 

According to popular Bitcoin price predictions, BTC is expected to reach its ATH of $68k by 2025.

9. Zcash (ZEC) - Cryptography Platform Providing Enhanced Privacy

Although blockchain provides a decentralized platform, most of its transactions are public. Since discretion is important to investors, privacy coins such as Zcash have become popular.

A key feature of Zcash is the privacy aspect, but it also provides fast transactions at low costs. The platform offers shielded transactions and keeps the user's financial information confidential. 

It's the first project to use zk-SNARKs, a form of zero-knowledge cryptography, providing the highest level of privacy. Although Zcash transactions are on the blockchain, it hides key personal information such as the user's wallet address and the amount of funds transferred.

Zcash secures its network by using proof of work mining algorithm, then rewards miners for the computation of each block with Zcash tokens and fees for transactions added to the block.

What Defines Proof of Work Crypto?

Cryptocurrency projects can choose between proof of work and proof of stake consensus mechanisms. Every transaction on the blockchain needs to be verified to avoid duplication and to ensure legitimate transactions.

A consensus mechanism acts as a system that connects all networks to ensure transaction legitimacy. It could be referred to as the central authority for transaction verification and as means for different stakeholders to agree to a transaction.

Proof of work is the original crypto consensus mechanism and requires a tremendous amount of processing power. Bitcoin, the first crypto to use proof of work, has received significant criticism for using a lot of energy consumption for mining. 

Virtual miners secure and verify proof of work blockchains by solving a math equation and receive token rewards for successful completion.

The Difference Between Proof of Work and Proof of Stake

Proof of work blockchain is regarded as the true consensus mechanism maintaining a secure decentralized blockchain by converting electricity into security. Using proof of work is an energy-intensive exercise, and it can struggle to process a large number of transactions that busy networks generate.

It is prone to 51% of attacks on the blockchain. To provide blockchain users with a safer, more efficient alternative, proof of stake was developed. 

Proof of stake doesn't convert energy into security. Instead, it requires crypto holders to lock up their assets so that blocks can be added. In exchange for locking up their coins, stakers receive more tokens as rewards.

A key reason crypto projects use proof of stake instead of proof of work is environmentalism. Proof of stake has been marketed as a secure verification method without vast energy consumption. Excessive electricity use isn't required, unlike proof of work.

One of the main differences between these two consensus mechanisms is penalties for network disruptions and bad actors. Miners using proof of work are penalized the sunk cost of energy and computing power for submitting incorrect information.

With proof of stake, validators have their funds reduced for accepting a bad block.

Are Proof of Work Cryptos a Worthwhile Investment?

Some of the most volatile cryptos use proof of work as a consensus mechanism. Yet, proof of work cryptocurrencies provide investors several benefits.

Proven to Work

Bitcoin is the first crypto that used proof of work for secure transaction verification and still does to this day. Proof of work has been around for more than 10 years and hosts the biggest crypto coins such as Ethereum Classic, Bitcoin Cash and Zcash.

Because it's been around since day one, proof of work is a more trusted mechanism than new methods claiming to be better alternatives. Its longevity has made it the perfect option for long term crypto projects.

Mining Rewards

Proof of work requires individuals to verify transactions. They are called miners, who use high-powered hardware and consume high levels of energy to solve a math puzzle. 

Once they've solved it accurately and added a block, they receive rewards in the form of the network's coin.


Miners are located globally and don't require a third party such as an exchange to receive rewards.

Using proof of work, instead of proof of stake, enables the user to maintain more control of the processing on blockchain, and it cuts out the middle man.

How to Invest in Proof of Work Cryptocurrencies

Investors can use the step-by-step guide below to learn how to buy RobotEra right now. 

  • Step 1: Create a Crypto Wallet - Before it's possible to participate in the RobotEra presale, a crypto wallet is required. While there are hundreds of options to choose from, in our experience, MetaMask is great for desktop users while Trust Wallet is commonly considered the superior choice for mobile investors. 
  • Step 2: Buy USDT or ETH - After setting up a crypto wallet, it's time to fund it. Both USDT and ETH can be used to purchase TARO, meaning it's up to the investor to decide which better suits them. However, it's worth noting that ETH will always be needed for gas fees. 
  • Step 3: Purchase TARO - Lastly, head over to the RobotEra presale website and connect the newly created crypto wallet. Following that, use the 'Buy TARO' button to open the purchase menu, decide how many tokens to buy, and confirm the transaction. Once the presale is completed. tokens will unlock at a rate of 10% monthly.


Our proof of work cryptocurrency list consists of eight of the best coins. But we found RobotEra to provide the most utility and offer rewards to investors.

Investors can now buy TARO for the lowest price possible during its presale and with many investors expecting it to be one of the best penny crypto assets in the coming months, it could be the perfect time to check out the RobotEra presale.
