Just found the other MicroCoin.... Arduino is trademarked, it can't be used here as our coin's name. It looks like MicroCoin shut down a few years ago, and has gone through 3 iterations. It seems incredibly unstable AND the forum thread is almost dead. I will consider changing the name though. Thanks for the info.
MRC
it is the house coin of a Finland Exchange
tech is fixed and very likely will be Top100
