For the most part - off the charts. I know a bit of background of each coin though to lean my decision on which to add more too.

I stopped researching coins about two or three years ago, it is a bit of a daunting task with the massive influx new coins that are coming out. With just 100 coins it became a full time job, I couldn't imagine attempting it now, but now I feel like I am investing blind and I don't know enough about reading charts.

In that light, then you are better off just holding some of the top coins and just going along for the ride and maybe speculate on one "new" coin. Kinda like long term buy and hold with stocks.

Thanks man :)
