Great article! I found it interesting.
Talking about ICOs, after doing your own research, also finding good ICO projects can be profitable.
I want to share with you guys a new exciting project I have just discovered: RAWG.
Check out this great article from Entrepreneur, one of the most popular business-related magazines, which has spoken with RAWG founder, Gadji Makhtiev.

RAWG is a blockchain-based platform for gamers that was born last year in the heads of Gadji and RAWG CPO Alexey when they found out that their gaming website Kanobu attracted users for their gaming database.
The ICO will start in a short period and they are at the moment in pre-ICO phase. This is the site: https://token.rawg.io/. It's a video game discovery platform that converts your skills into goods and services (the site is already working, with more than 57,000 games in the database).
Have a look and get some information while doing your own research :)
