I think this coin is dead and buried.  They had a "hack" a couple of months ago and lost a bunch of money.  They "claim" one of their Dev's left a laptop open and unattended at a public location, which was logged into their site, and someone walked up and made off with a bunch of BTC and other funds.  Some claim it was an inside job but I don't really know the facts, just what was posted on Discord before they shut it down.  They claimed they were in the process of refunding stolen funds.  However, they seem to have totally disappeared now.  My guess, and it is just a guess, they were in too deep to refund the money, closed shop and left town.  Too bad.  I have thousands of MCT coins and was getting some decent POS rewards.  The coin was pretty much worthless though.  It wasn't being traded on any exchange.  Would be nice if they came back, but when a coin just abruptly goes dark like this one did, it is probably another coin for the "what ever happened to" file.
