It seems that the situation is getting from bad to worse by each hour. This is not a normal trading so to speak of any support is pointless. The support is when the last bitcoin of Greyscale will be sold. I won't be surprised if we see covid like apocalyptic dump. Too bad I don't have any fiat left to buy moar. I guess the plan is to keep the rate 1.5% until the BTC outflows stop. And then lower it to 0.3%. But people are not so stupid to return to Greyscale knowing that they will raise the rate again.
