The Bitcoin mining marketplace is competitive. Committed mining gear has made it impossible for small miners and amateurs to compete with significant mining pools, also with fresh ASIC units being constructed and published on a monthly basis, the times of CPU or GPU mining — on the Bitcoin network — are all over.

Luckily, Bitcoin is not the sole cryptocurrency from the blockchain ecosystem. It is still feasible to mine countless distinct cryptocurrencies with easy GPU replacements — in some instances, CPU mining remains workable. The most significant question to ask, however, is whether GPU or CPU mining remains rewarding. We’ll move to assess the present condition of CPU and GPU mining and emphasize the most promising option coins to mine with no ASIC unit in 2019

CPU miners are now locked from this Bitcoin mining ecosystem, but there are still numerous coins which may be mined through CPU alone. There are a range of factors which needs to be considered before CPU mining any coin, for example mining issue, cost volatility, market capitalization, use cases, and programmer background, however the blockchain ecosystem is home to countless promising jobs that rely upon the attempts of exploratory, forward-leaning miners.

The growth of this ASIC has also caused the creation of many efforts made to thwart ASIC monopolization. The Cryptonight algorithm, as an instance, was made to be mined inefficiently on ASICs, and is concentrated on establishing genuinely decentralized blockchains which may be mined by almost any network player.

Finally, CPU mining altcoins at 2019 necessitates careful analysis and the capability to identify promising cryptocurrencies that provide mining ROI — there is no purpose CPU mining inconsequential altcoins which are destined to be cast into the deadcoin graveyard, however rewarding options still exist.


Monero is among the very well-known cryptocurrencies which may be mined with through CPU or GPU. In mid-2018, the Monero network hash speed increased dramatically following the development and launching of cryptonight-friendly ASIC miners. A Monero hard branch in October 2017, nevertheless, quickly eliminated ASIC involvement from the Monero network.

Monero has switched from cryptonight into cryptonight V7 so as to thwart the Antminer X3, but further afield ASIC immunity by implementing cryptonight V8 — CN version 2 and quite a few additional routine changes.

Even the”Beryllium Bullet” update, or V8 Hardfork delivered a significant increase in efficacy for Intel CPUs, but also contained updates that bricked some present cryptonight7 ASICs and created the creation of cryptonight V8 ASICs prohibitively pricey.

Bitcoin Gold

Bitcoin Gold is a difficult for of Bitcoin made particularly for GPU mining. To be able to advertise a hash power transfer from large scale ASIC farms, Bitcoin Gold changed from the SHA-256 algorithm to Equihash, which favors GPU exploration.


Horizen, such as Monero, is a favorite privacy-focused blockchain which permits users to send and receive transactions anonymously. Notably, Horizen now gives the maximum degree of reward among Equihash coins.


Zcash mining takes up the biggest portion of hash electricity targeted at Equihash coins. Interestingly, Zcash mining is now more rewarding than Bitcoin or even Ethereum mining, but does face numerous inflation problems.

Using a power consumption of just 100 watts using a mean price tag of $0.12 kWh, it is potential to create around $85 yearly at present Zcash rates. If scaled in a efficient fashion, Zcash can provide a compelling ROI into GPU miners.
