I’m a capitalist at heart, Caiof, so I have no problem with someone making money. The problem I see is called the tragedy of the commons. This is where something that belongs to everyone is taken over by a few users. Pollution is the easiest example to name. The commonly held property is destroyed and the value is taken by the user.
This same thing can happen in cryptocurrencies. The potential belongs to everyone, but the speculators can take that potential and pocket the money to be made. Someone with an idea to really do some good then does not have a chance at an ICO at that point because the only ones in the market are those who only want to make money.
My concern is that I see this happening already. Like I said, almost all the posts are about how this or that coin can make money. Again, making money is not a bad thing, but if that’s all this technology becomes we will lose a great opportunity.
