Just wondering if anyone has noticed a trend of longer block times when the price drops. I presume some proportion of miners become unprofitable. And that of those - some might need to convert to fiat in the short term to cover costs and so pause mining.
There are lots of Solo miners who will be very happy if major mining farms take a break just even an hour due to the fall in the price of Bitcoin, so with regards to the question of do miners drop when the price of Bitcoin drops, then I will say they don't, because considering how much these miners generate after mining each block, it's enough to cover any loses caused by a recent price drop. However, I just checked the recent block mining, and all I could see are still the major Bitcoin miners, which is a clear sign that no miners left due to the fall in price of Bitcoin. Example, miners such as
AntPool, SpiderPool, F2Pool, and Foundry USA Pool., which have been known to consistently mining the recent Bitcoin blocks.
