I would agree on this, if @op feels that the market of quant will surge then he can always have the option to hold, or you can sell part of your holdings in order to at least take profit then hold the other part for possible price surge in the future.
@OP, you can always try to buy at centralized exchanges, Binance has a cheap withdrawal processing fee so you can try buying on that exchange or try what tabas suggested.
He doesn't have to rush if there's no immediate need for him to sell that. But if the circumstance permits it and he truly needs it, then he can just buy on those usual exchanges that we used to have.
