I am also hoping that the 26k+ wick a couple of hours ago would be the new low and that a good recovery would happen. But yes, just like you I also see bitcoin going as low as 21k-20k+ levels. If the selling pressure continues and the bulls still don't take action, we may really see these prices again. But, as unpredictable crypto is, I also am expecting a move upwards half way through the month. So being in this unpredictable market, continuous accumulation and DCA is the most hassle free and effective way to gain profits in the long run.
I do not see it going down that long, the Luna deal is basically done, they have dropped like 99%, how much could it lose, how much money could get out of it? Luna team basically milked every single cent they could from it, and they are now emptied, they can't sell more to make more money to recover USDT.
The weird thing is, from here on out, I am pretty sure that UST can't be saved neither. They sacrificed the price of Luna in order to keep UST a bit higher, but now that Luna can't help them, they can't defend UST neither. So, the drop in bitcoin will stop, Luna will not recover, UST will fall and everything else will go back to normal.
