after reading all the posts here about substratum I´m still asking me if I should invest in SUB or not. I like the idea of SUB, they want to solve the problem of the NetNeutrality. On the twitter Account of SUB there is a video how it will works. In the US they already banned the NetNeutrality, so there is a huge market.
If you want to make money AND support the cause, I'd jump on the rocket right now!
