Hi.
I was looking at the hashrate vs price chart and I am wondering if there actually is any correlation between those two. If hashrate drops significantly do you think it would affect BTC price at all?
You just have to look at the recent crash this March, and you will see that there are correlations. When the price goes down hard, the hash rate also decline. I think you can start your investigations from there.
In other words, the hash rate can't be used to predict the price of Bitcoin according to OP's interest but it's possible vice verse as Hash rate follows what happens with the bitcoin price.
so I guess not so many miners closed their mining farms.
If you noticed, immediately after the halving, the mining fee was high and it still is during weekdays. So, even after halving of the block rewards, there is still enough incentive to keep the miners happy in form of transaction fees and if there are miners who closed their farms, I don't think they are many.
