You're still early to the game.
You think I'm still early? That gives me hope.
Oh yes, you're early. The end game for crypto is mainstreaming: you can see the first steps being taken in recent news. Once it's too late, crypto will prolly be regulated just like everything else. Allow me to present the Iron Rule of Mainstreaming: when you meet the mainstream, you meet the demands of the mainstream.
Right now, the "crypto-economy" is still largely unregulated. (Fiat gateways are another matter entirely) I know about BitLicense, but it's only a first shot in the dark. Myself, I won't say it's too late until the United States has a new regulatory agency, something like the SEC, that oversees cryptocurrency. That would be the too-late moment for me.
You'd do best to stick your toe into the water by looking at
Coinmarketcap's top 20 and crossing off the list any cryptocoin that's less than a year old. (An arbitrary number, true, but it's good enough to weed out the hypecoins.) I suggest starting your research with those, as they're likely to be less unsafe.
