I think HODL is the name of the game for most people in crypto. Atleast for those who are in for the long haul.
That being said, I always have few hundred dollars worth of BTC lying around for day trading. Nothing like riding the market to remain in touch with it.
PS: eight percent is too much to be true.
I trade a little too but I am slowly trying to build some kind of diversity in coins at least.
I went a little crazy last year and now have more than 25 coins - I know it's crazy but half of them are actually too little to affect my portfolio substantially.
