I would like to remind all my friends in the front row not to short the altcoins, don’t short it, don’t short it.
You can short BTC, ETH, but don’t short the altcoins. Although the altcoins will eventually fall, there is no limit to their rise. They will blow up most of the short positions and then kill the long positions, unless you are a dealer.
Don’t touch the altcoin contracts either. You can take the spot. In the long run, the most stable way to make money is the spot.
