Logically we know that when the price of crypto falls it acts as an investment opportunity and that is the time to invest there. But at different times it can be seen that different coins are scammed at the last minute but since Bitcoin is one of the first coins of cryptocurrency and known as the godfather of all coins, Bitcoin will never become a scam, so now the price of Bitcoin is very low and the market is very dip, so you can think about investment now.
To me, a good speculator could invest in Bitcoin at any time whether by buying it or selling it, the opportunities are always there. It is you that did not clarify the investment you refer to, and I believe it is to buy and hold. If that is the case, this might be the right time because the coin seems to have bottomed already. Though no one should be so relaxed about this, as the coin is bought, regular speculations about adverse developments should be considered.
