here is a post of mine which looks at a mock portfolio based upon cryptos that haejin said would go up, it also links to the portfolio. I would like to notice that the portfolio itself is not doing so hot and that if someone had put $100 in each of these cryptos (in January) then the total value of their portfolio would be around $250 less than what they spent. Haejin's past predictions were only considered good because it was a bull market where everything was going up and you could roll a super special 52000 sided die (each side with a different crypto on it) and chances were the crypto in question would rise in value.

So, HODL for sure but I would really recommend that you do not use the advice of Haejin.
