I do agree the gain in value in crypto will likely be much higher than any traditional investment. Question is: Which coins will do good and which coins will end up worth nothing. My reality is that most of the coins around today will end up without any value. Amongst them maybe even some of the top coins of today.
With the concept of crowdfunding, everybody is able to invest small amounts in companies. I'm talking about those crowdfunding platforms offering convertible loans or equity. With 10 dollars one can already participate; At least on some of those platforms.
