I want to broaden my horizon as well, therefore I started here on steemit. I see writing here as an investment for the future. And since I enjoy blogging, why not make a few bucks on the side, without annoying people with ads. However, in 2014 everything seemed like a mess. So I invested in people, not currencies.

Btw, it isn't that I don't think that Ethereum can scale, I just don't think that the tech behind it is anything special anymore.
Considering how fast so cyrpto projects are moving right now, nothing created is going to stay popular for long I reckon. Even if someone comes up with a great idea to do something (e.g. ETH with ICOs), someone else can come up with a better/faster/more secure way of doing the same thing.
