A very big THANK YOU to everyone who has replied!

Some people were against certifications. Or against paying for them. I just wanted to bring to everyone's attention that Andreas M. Antonopoulos and Vitalik Buterin are on their Board of Directors. So it's not some scam IMO.

Secondly some of you have pointed out there are free courses, too. I decided to look at them first.

And then some people also wanted to join this study group. I tried to DM you but I couldn't (not allowed since I'm pretty new here). Please DM me.
