I'm looking forward to store some stable coin for future investment, maybe probably when a harder bearish market takes place to buy coins for lesser price but I can't seem to figure with stable coin can make me have a good night sleep at night with zero worries, USDT? BUSD?
I think that both stablecoins that you have mentioned should be pretty safe i mean in the end you can never be 100% sure but if we really assuming that USDT or BUSD are going down to 0 then this will drag the whole cryptomarket down with them and it would take a lot of time to recover from that in my opinion. The only concern with USDT is that it is not clear anymore if every USDT that is minted is really backed by a real USD anymore because the team of USDT changed the wording a few years ago from "every USDT is back by real USD" to "we have enough reserves to back every USDT by a real USD" but no one really knows what that means.
USDC are also a good alternative.
