I have decided to not invest into Arcblock and Gems. You will find my reasons in the OP.
These are my thoughts of them. If you disagree, that is fine. I can very well be wrong.

I've learned a lot the past couples of weeks looking at ICO's.
I'm sure I still make mistakes, and we will see in a year if I made any good / bad choices.
Only time can tell. But for now I'm threading carefully. Potential is everywhere. You only need to spot them before it's too late.
