Is only an immature trader that sees bull times as the only or appropriate time to make profit in trade. A good trader makes profit even in bear market. He/she milks the market at anytime he is convinced for a trade.
It is true we could use the market to get a profit a great trader doesn't stop trading whatever the market situation is.
A great trader would always find a way to get a profit.
Besides if you want a great profit you should have bought some when the market was still bearish and crypto was still low price.
