The best chance to profit in the falling bitcoin market is to short it. You can do this by using 5x - 10x leverage to have a very high liquidation price. Then, wait for Germany to dump all of their remaining bitcoins, and you will get decent profit from shorting the market.
Though, this pretty much the same like catching a knife, but it's gonna be really profitable. And last, im sure bitcoin won't be bullish before Germany governmen will run out of their btc
Future trading is one risky trade that I can advise anyone to go into. The risk is just too high, just as the profit margin can also be very high sometimes, just like the BTC market has started reversing a bit to the upside, moving from $56k to $57,700, which it is currently, and if someone is going short with BTC in a future trade by now, they will be recording a little loss, and if bitcoin eventually crosses $60k, the loss will be higher.
