Actually if you are a professional investor, you can earn money both in the bull market and down point. The most boring is a market siderway, not the market down.
In strong declines, there is always the opportunity to go a long way in the opposite direction, so anyone who knows how to play in a down market will be rich quick in a bull market.
The important thing in a bearish market is the trend reversal, so remember that in the bearish market and as close to the important support points you should put extremely short SL. For this reason, you can lose 8 out of 10 orders, but just succeed 2 orders, you will get back all, even profitable.
So for a professional investor, you can make money even in a strong down market.
Prepare yourself for a solid strategy and psychology. Good luck !

yeah we can gain money when the market drops but in a low profit,sometimes will turn inot loosing of your capital or trading investment,bit as long you are technically creative and know how to analyze the playing movement or the statistic data of the exchange market price,then you can continue to collecting profits in some of you invested crypto coins,because its need only an technical analization and strategy on how to handle in this bearish situation.
