How did you decide what altcoins to buy? I assume you bought more volatile ones?
I'm considering doing this, as a college student I don't even eat a lot anyway so.
I do a ton of research and pick projects I think will grow.
A couple of key points that help when evaluating new coins is to look at similar projects and check out their value, circulating supply, and dev activity.
It doesn't hurt if you can read, understand, and compile the source code.
I like to get in alts when they are just released.
If I can get them for 1 satoshi then the value can either go to zero or up.
