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...
The whole idea of a "stable" coin is flawed because it depends on external factors which in turns creates a distortion which grows and grows until it breaks. It is the same reason pegging a fiat to another will end up the same way even when enforced by the State (if you check history, behind hyperinflation there is always a pegging). The so called "volatile" price of Bitcoin is a honest market price, as shown in the long term graphs, its a steady climb. The people who don't understand fail to realize fiat is a descent (by design, infinite emission).
So it either breaks because their reserve was too low, because someone played with the reserves, because code failed to react to external events or data came "too late", etc. Pegging always breaks sooner or later, you are simply being blindfolded from the truth, just like a PPS pool...
There are too many elements that can make a peg break, and they all do sooner or later. So its best to not peg in the first place. To add insult to injury, almost none of those "stable" coins are "tokens", meaning they don't even have their own blockchain to begin with. It is hilarious that some even peg against each other so things like Luna occur.
You could argue it was not Circle's fault the bank they choose to put their reserves failed. Of course they can fail, they do fractional reserve. Guess who also does fractional reserve? That's right, Circle. None of the badly called "stable" tokens do 1:1 and even if they did, the other external factors (like in this case, a bank failing) could hit them regardless.
Do you trust your bank? Why trust these? Don't trust, verify: Bitcoin. P2P electronic cash, no banks, no exchanges, no State. Its not a mere asset...
