I've not heard of 21Million Coin, but will check out your post.
I am not an ICO veteran. I've recently allotted a small percentage of my net income to dabble in cryptocurrencies. The CIVIC ICO was the first one that I attempted to join.
Prior to that I've been buying/holding BTC, ETH, REP, and Golem. I've done a fair amount of analytics for my day job, and have spent several of the past years focusing on asset diversification in Stocks/Bonds/REI etc. I wanted to see if any of those skills translated to crypto.
I did not realize that EOS would not allow individuals from the US to participate. That's unfortunate if true. I had been considering a strategy in how to invest over the course of the ICO period. I do have some serious concerns about a potential spike/crash with EOS so perhaps getting in at the post crash floor will work it (if it occurs).
This is the first I've heard of metamask, but I'll check it out as well. Thanks for the referral. I started with Jaxx since I liked their ShapeShift offering as well as their cold storage device. I like the idea of putting my keys in a bank safe so I'm less tempted to day trade with them. :)
