It's probably a good start. Those coins have traded pretty well. What I've always had in mind when it comes to crypto currencies, and investing in them is to not risk money you can't afford to lose, and look for ways to recover capital, and after that, it's profit, and if you lose because the price drops, it's not really a loss, it's already recovered. And of course, you don't lose until you sell it at a price less than you bought it.

These are basic rules that I learned a few years ago.
