Sure, you might snag a few wins, but in the long run, you WILL get rekt.
Bitcoin is an unstoppable train. If you don't believe in its power, don't hop on.
But here's the golden rule: Never bet against Bitcoin.
Bitcoin stops many times and in bull run, it has many corrections, draw downs. If you short Bitcoin around its correction, you will get profit and remember an important thing if you open a short position. Short position is for a short period of holding that position so don't make a short position and let it opens for some days, weeks, you will definitely get rekt.
Time is important with short positions but best is don't use leverage. Because you can not short Bitcoin if you use Spot trading which is a trading type you should use, not leverage trading or futures trading.
