My honest opinion is that Bitcoin still hasn't got to its purest form and price therefore wherever you buy, hold or sell, Bitcoin is going to move up in the future. There is still a lot of integrations and usage implementations are going on, like El Salvador is implementing BTC as a means of currency so with time the price will go up.
At this time it seems you can say the price of bitcoin is experiencing a correction,
so indeed we can see currently the price of bitcoin is falling and the price of other coins is the same,
With this I don't think there's a better choice than to hold on
