Holding your cryptos and do not sell them in a panic way! And if you may also take this opportunity to find some really better options and make some adjustment to your portfolio. And do not try day trading or short trading if you are not really good at it as it may drive you crazy in such a bearish market. For me, it will also transfer some of my assets into USDT and try to but some dip when it is relatively stabilized. And the other thing is you should be really picky when investing in some ICO projects as things are different this year, you can't expect to gain 5 or 10X return as it is used to be!
