Ethereum Mining vs. Bitcoin Mining vs. Litecoin Mining

Blockchain technology and cryptocurrency, in particular, are captivating the world. From Bitcoin’s market performance in 2022 to Ethereum’s versatile smart contracts, cryptocurrencies are generating global buzz. While these two leaders dominate the conversation, other coins, like Litecoin, attract investors seeking potential gains. This influx of interest fuels the growing popularity of Ethereum mining, alongside other crypto mining activities.

As part of the wider cryptocurrency discussion, this article delves into one of the defining concepts in cryptocurrency: mining. Specifically, we look at how the top three coins undertake mining, comparing algorithms, mining equipment, reward system and so on.

We first discuss the above concepts in relation to each coin and then summarize by drawing a comparison table.

So, here we go

Bitcoin Mining vs. Ethereum Mining vs. Litecoin Mining – Mining Algorithms

Bitcoin uses a proof-of-work consensus algorithm to secure and verify transactions on its network. Miners (nodes) on the Bitcoin cryptocurrency use the SHA-256 consensus algorithm to complete and add valid blocks to the blockchain. The mining difficulty in Bitcoin is adjusted after every 2,016 blocks or approximately after every 14 days.

Ethereum on its part uses the Ethash algorithm which is a memory hard algorithm. It is designed to favor decentralized mining using ASIC-resistant hashing mechanism. At the moment, Ethereum is switching to proof-of-stake with the implementation of Casper protocol.

On its part, Litecoin mining involves the use of Scrypt algorithm. It is a memory hard algorithm that was designed to counter the development of ASICs as it was happening with Bitcoin. Litecoin’s Scrypt algorithm was developed to favor high speed RAM and was ASIC-resistant at the beginning though that has changed with time.

Bitcoin Mining vs. Ethereum Mining vs. Litecoin Mining – Block Transactional Size and Time

For Bitcoin, the block size is set at 1MB, though there have been calls for it to be increased to 2MB, the issue leading to a hard fork in 2017. The small blocksize has been cited as the reason Bitcoin has a big problem with scalability and huge transaction fees. Bitcoin blocks are verified on an average of 10 minutes, though the Bitcoin network can process up to 7 transactions per second.

Ethereum’s blockchain comprises of blocks that are variable in size. Mining blocks occurs at a rate of approximately 12 seconds. The Ethereum blockchain can process up to 25 transactions per second. In terms of scalability, Ethereum’s blockchain is way better than that of Bitcoin. Ethereum costs transactions based on storage needs, the complexity of each transaction and the bandwidth usage. This is called “gas”.

Litecoin’s block time is 2.5 minutes compared to Bitcoin’s 10 minute confirmation time. This means that the transactions on the Litecoin network are completed faster than that on Bitcoin’s platform. Litecoin can have up to 100 transactions per second.

Bitcoin Mining vs. Ethereum Mining vs. Litecoin Mining – Coin Supply and Block Reward

The total maximum supply of Bitcoins is set at the hard cap of 21 million coins and the mining reward halves after every four years. It was 50 BTC at the beginning, then 25 BTC up to 2016; today its 12.5 BTC and the next halving will be in 2020. The total circulating supply of Bitcoin is 16.8 million BTC (as of 15 February 2018)

Ethereum does not have a maximum supply. Currently, there are 97 million ETH coins in circulation. The ether miners get 5 ETH as reward for every successful transaction verified on the network. The implementation of Casper will replace mining with “staking” and there has been a talk about limiting the supply of Ether to just above 100 million coins.

Litecoin has a hard cap supply of 84 million LTC and right now there are 55 million coins in circulation. Litecoin block rewards halve every 4 years just like with Bitcoin. The current block reward is 25 LTC for every valid block added to the blockchain.

Bitcoin Mining vs. Ethereum Mining vs. Litecoin Mining – Mining Hardware

Bitcoin’s SHA-256 algorithm allows the use of ASICs in mining. The development of ASICs means that ordinary miners cannot carry out mining unless they join a mining pool. This scenario has prompted the formation of mining farms, some of which command immense power. Though not inherent, mining farms can pose a security threat through the acquisition of 51% mining power. It is also criticized as a centralization of the network.

Ethereum’s use of Ethash mining consensus means that the system promotes the use of GPUs in mining. Ethereum mining is unlike Bitcoin mining because of its memory hard hashing that is ASIC-resistant. You can carry out GPU mining effectively on the Ethereum network as opposed to Bitcoin. However, these will all change once Ethereum shifts to Proof-of-Stake consensus mechanism during the launch of serenity.

Litecoin, on the other, hand has an algorithm that was designed to allow mining with RAM units rather than processing power. Being memory hard, Scrypt supports the use of CPU and GPUs for mining. However, like Bitcoin, some miners have found a way to develop ASICs that target Litecoin mining. At the moment you can still mine Litecoin using GPUs compared to Bitcoin where ASICs dominate.

Conclusion

Bitcoin mining vs. Ethereum mining vs. Litecoin mining – which one has the highest profitability and ROI when all factors have been considered? To get this you would need to calculate the profitability index of each coin, bearing in mind the hardware type, hashrate, as well as the electricity costs.

Though not as profitable as in the beginning, mining can still work for you if you have the right equipment you are good to get started with mining. If you wish to try mining of the above three coins, you should consider the above factors. Check out miners here
