Ask to the gamers who cannot buy an RTX video card because of that!
They also cannot buy those video cards because of the worldwide chips shortage.
it is fair to draw that the difficulty will drop.
The difficulty drop is small and for the miners, although it makes mining a tiny bit easier, it decreases the revenue from tx fees. If we talk about small percents, this fits in.
I don't think that it'll make such a difference.
What will be the consequence for the BTC value?
My guess is that it will raise, because of that. The market should take this in account in advance.
Coins mined easier should mean the miners can sell cheaper.
Also since tx fees will drop, it will also be easier for weak hands to sell.
So the price should fall by your logic.
But I think that it has fallen enough, the rebounding will continue and the small change in difficulty will be basically unnoticeable in the price.
