Its probably not the best strategy to sell when everyone else is panicking and selling. You can read the memoirs and guide of any investor book, all successful investors buy when the price is low. WE cna speculate all we want about the Chinese intentions, including creating a low entry point for themselves as they felt that they missed the boat.
The reality is that if you believe in the fundamentals of bitcoin and crypto, now is a good discount on prices that we are having. Do note that short USD (expecting USD to fall) is also one of the most crowded bank trade at the moment. Any USD related invesment is probably not the wisesest either.
