Nothing else, but Bitcoin alone.
Since were in the bear market at the moment, Bitcoin is about to hit the floor like a drunken teenager. It will most likely lose the most out of all crypto coins and all eyes should be on BTC during that time.
Bitcoin is that coin that shouldn't be neglected at all, instead you should short it whilst its going down.
Thats where one makes money whether one trades or invest in a bull market or a bear one.
Sure, you can go ahead and short alts, too
