Quick reminder: After every single block halving, obviously the BTC that's being decreased block decreases as well. I'd like to play devil's advocate(though it shouldn't really be controversial) and say that the next halving would have less positive market effect compared to the past halvings.
So it is! With each halving, the share of new coins in the total volume is halved. Consequently, each subsequent halving has less and less effect on the market price of Bitcoin. Therefore, mining plays an increasingly smaller role in Bitcoin pricing.
I said it for the last halving and was wrong, but I might be correct for the next one, sooner or later unless the price goes and stays high enough the lack of rewards is going to kill some big mining businesses.
POOLS don't need a lot of money, yes a fair amount, but servers and such are a fraction of what it costs to have the infrastructure to run a data center full of miners.
Seriously, I was convinced that going from 12.5 to 6.25 would take out some more places then it did. But, with covid and everything else going on at the time it may have distorted some financial things.
But for the next one, since we are seeing some big mines teetering on going out of business, loosing another $60k per bock might just push them over the edge. Which is good, it would bring mining back to the people so to speak, if enough large mines shut down then home / hobby mining even if it never becomes a real source of income, at least does not stay at a just about guaranteed loss.
