You should never bag hold stable coins in first place considering how risky they are since they are all more or less centralized with shady companies behind the project controlling everything there is about the coins in and out of circulation. If you want to go out of the market then convert to fiat instead while only using stable coins when you have no other choice.
As for bitcoin price, what we saw was actually very common when a resistance is not broken (ie. $25k) and it is not a big drop as some people may think. It was retesting the support once again and so far it has not resulted in any actual downtrend (price is still at $20k that is the support).
Of course we have the negative news and the FUD to contribute to that fall trying to make it bigger and failing, so far...
It's a logical action. Stablecoins are good to use as an exchange currency. You won't find any other use for them.
