Dbrain is a good ICO from the list you shared with us in my opinion.

Another good one that I would like to share with you guys is RAWG. The ICO will start not in April, but in May.

The ICO site is this one: RAWG. It's a video game discovery platform that converts your skills into goods and services.

You can earn tokens by playing your favorite games. The site is already working, with more than 50,000 games in the database and new games are getting added every day. This is the site: https://rawg.io/

Quite good looking, don't you think?

They have just started a very rich Bounty program for everyone who is willing to participate:

with a nice referral program that can double your rewards.

You can also join the airdrop here.

I hope this information is helpful!
