Everyone decides for himself when it is best for him to buy or sell his cryptocurrencies, but the most reliable option at the moment is of course to buy cryptocurrencies when the market drops sharply, which has been happening for almost two years, and when the market starts growing again and then there will be the best option for the sale of your cryptocurrencies, if you do not want to hold of course even longer.
I agree on such a sharp fall, even Bitcoin, why not buy it for $ 8,000. I think that this is a very profitable investment now, because it is very difficult to invest in business.
Bitcoin is very expensive now. I would wait before investing in anything on the market.
