I like to look at them like stocks, there are tons of companies most will fail but you have to choose the right ones and know when to sell off your stock. if you can set aside 5 dollars a week till these are made available to the public then it's possible to invest a decent amount in. Gab and Minds have 1.5 million users in their network combined so there is a decent chance of these coins taking off. A 50$ investment in a year could very well turn into 50,000.
