Ya miners are one tough sons of a b*tches group. Price of eth dumps 10x but hashrate only dumps 10 percent.
Mining will live on. Just everyone gets fractions of a peanut profits if any.
90% of eth miners are mining at loss, 9% are breaking even and 1% is earning peanuts per day with their gpus. The hashrate difficulty is proof that people believe eth will rise in the coming months a lot cause most of them are losing money mining it, best thing is just buy the coin and wait for 2020/2021.
