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 !
Investing in crypto is different with currency or commodities ( forex ), in forex you can do that but in crypto is impossible. Crypto is one direction ( buy - sell only ) and I don't see any strategy besides that except you're exchange. If you can make money on drops market I believe you're never show/ share on public ( silent trader/ investor ), trust me.
