... in continue to missing coins, youpool team replied about the problem:

youpool : Not sure why... maybe the pool is forked when paying out.
me: I suppose, you will fix it and will send me missing coins?
youpool : No, you should have recieved your coin after the pool on the right mainchain. All the valid coins has been sent you. When folk, the pool sent you 1000, which is not valid. When the pool on the right chain, the pool sent you another 1000 coins. Your wallet shows 1000 coins, however the pool mining webpage shows 2000. So, you should have receievd the coins you mined.
me: Who have to restore mined coins?
youpool : The coins sent when the pool on the wrong chain have been invalid. So, no one has those coins.
me: This sounds like robbery, the pool shoes paid coin .... This can happen on everything i mine on your pools
youpool : Sorry, it only happened in this pool....because only tyche always fork...

So could you tell me what a hell I'm calculating when the pool is on wrong chain, who gives this wrong chain ? Who is responsible for non paid mined coins ?
I suppose that everybody understand that this could happens on every miner using youpool or Tyche ? Have no control here, and respect to the miners. I think this you are calling "SCAM" pool or coin?

DEV, I suppose if you think to develop serious coin, you will have serious answers. And still I expect the coins I mined ...
