I am having a hard time doing that. Any time I pick up a coin or ICO and do some research about it all that I found out is rubbish behind it. Yet they still keep rising. It looks like a fucking gamble to me.
You do what I believe is called "Value Investing". Not so much the fundamentals of a coin, but the team or devs behind it, what they promise to do, and what the public thinks about them, or what you think the public thinks about them (you can't really tell.) You try to predict which one will rise. Get in the mind of the pump and dumpers, without being them. I mean, I don't participate in the troll box or other forums, but I read them all, or mostly.
In short, it is gambling. LOL. Sorry. My so called "equivalent" 50 BTC is now 70, but as you or someone else has pointed out, it is not yet realized, so ... I better trade some of these back to BTC soon.
