Is GPU (Graphics Processing Unit) Mining Still Profitable In 2018?
With the attack of ASIC miners, GPU miners have been set aside, plus with all the new possibilities with ASIC miners most miners said goodbye to their GPUs, but does that make your revenue decrease?
How Bitcoin Mining Works (With Pools)
Bitcoin mining might be confusing to some so let me explain it in a more "noob friendly way". With a pool you and and number of people are looking for an answer to a very hard math problem, lets call the answer a needle in a HUGE hay stack. With more power means you look through the hay stack faster than somebody with a lower power level. Whoever finds the needle has to share its earnings with all the other miners in the pool but heres the catch. Earnings are split depending on how much you searched. Less computer power = less searching. So someone with a ASIC rig (more searching) could earn 0.005 BTC while a GPU miner (less searching) only gets 0.00000005 BTC
With more people buying ASIC miners it gets harder for any GPU miner to make profit. Now that does not mean that you can not make a profit, you can increase your hashrate (how fast your searching) by overclocking, increasing ventilation, etc.
The GPUs Demise
Sooner or later there are going to be to many ASIC miners, and GPU miners will earn close to nothing. Its just how the cycle goes, hey remember when CPU mining wasn't garbage?
The Final Verdict
Even though you can still earn money by overclocking, upgrading, and venting you GPUs they are slowly going to earn less and less until no one will be GPU mining.
