You can mine your own crypto coins, you can buy them for fiat money at an exchange or you can just register to a new and upcoming coin and help them get some more exposure for some free coins. Yes, for free.
Although it is totally not the way I imagine the future of crypto will look like, just getting some free coins is always a good idea if you ask me.
So why not get some for yourself guys and girls?
Register for an account at Signals for instance by following this link. Yes I will get some extra free coins as well, but it costs you nothing in return. Just register and follow their Facebook page, Twitter account and like some posts and/or tweets and you will get free tokens that will be exchanged for free coins over time.
Or take a look at Aelf coin, they are doing almost the same thing. click my referral link here. Same thing here, register, link your Twitter account, Github account, join their Telegram group, like some tweets and every 24 hours they will give you free coins in return.
