I suggest you dare to buy crypto now, look at the market so we will believe that the bull run is coming soon, if we wait then we will lose the opportunity to get big profits.
I think the answer is simple, but it refers to the time when you SHOULD NOT buy cryptocurrencies.
Naturally, it is the time, when the bull run is the fastest, and the cryptos almost reached (or reached) their maximum. However, it is not also good to buy alts and BTC when they are falling. The bottom is unknown.
Invest in crypto when the market has just started going up.
