that is why miners who will survive the next culling need x2 hashrate to stay alive. 1080ti to 3080 is an example.
those who have low hashrate card but do not have physical space to add more cards and those who do not have electrical space to add more load will be the first to go.
if eth is no longer profitable to mine, the eth mining reliant cards (amd) will be on life support.
3080 cards (nvidia) that will do well on other algo will do better than others hehe
Even if eth is around $1000, not sure if it will be enough to make up for, eth will have to be at least 1500 usd to be more or less profitable. Well on the positive side of things, 4gb gpus will be gone forever hehe but i dotn think 4gb gpus comprises of 50% of total hashrate hehe
