My love story with Middlecoin is definitely over since I saw it doesn`t pay unpaid (after 7 days).
I thought it is up to that I`m mining on different multipool now (which is pretty much more profitable), so I returned for short time just to start engine on Middlecoin, and return what thez own me.
but alas, my unpaid was flattened to zero as soon as my user statistics was updated ?!
I`m not returning to Middlcoin, never again - big shame for once great, the best multipool.
