Innosilicon just released a 500 mhs miner at 750 watts, no sure who is buying a it with progpow algo change.
Yes its pretty crazy how unfair the mining game is towards the ASICs. Basically most of my old RX series rigs were all RX 470 GPUs. And each rig used about 750 Watts, give or take. However each GPU peaked at 30MH/s, usually a little less. So my total hashrate was 180MH/s or so.
So if you compare it to the ASIC, its basically almost 3 times more efficient per watt than a GPU. Now this is why something like ProgPOW is important. Because if it had the same efficientcy then it would be fair and I wouldn't complain. However just like with BTC, the efficiencies will always increase and before we know it there will be ASICs which are 10 times more efficient, then 100 times, then 1000 times and eventually GPU miners will be completely out. This is pretty much to what happened with Bitcoin in 2012.
That is why , whenever ASIC enters the game, it's game over for GPU miners. And this is why i've always hated ASICs. ETH devs care from 0 to nothing about this problem. I don't even think they will apply Progpow. They will go directly to POS and reduce reward to 0. Almost 100% sure they will let ASIC destroy profit for GPU miners.
Efficiency wise and all this "climate change issue", they surely think it's better to have 1000mh/s using 1500W, than 1000mh/s using like 4kW or more. This madness is already too big to deal with it. Profitability is just a joke. And i aggree. This increase in hashrate is ASIC related, almost 100% sure. Noone is building GPU mining rigs with POS incoming my 1Q of 2020. Innosilicon is doing what bitmain did and has continue doing for a long time: design their own machines, and put them online winning extra money. First for mining, and second for cleaning and selling "old hardware" for people once they had a more powerful more efficient one online.
This is not what crypto was about. it was not created for being centralized, but it's the most centralized market you can ever imagine. 55% of all BTC hashrate is in China. Even with the ban, chinesse people are moving away their hardware to places where there is no such control.
