There is no problem with this coin?

I've 20MHs (hashrate about 5x R9 290x in X13 language), and I've won 50 SHOPX on 2 days...

Value of 1 SHOPX actually in Poloniex: 0.00003004BTC.

In 2 days of mining, I've won 50SHOPX x 0.00003004BTC =>>>> 0.000751BTC per day for 5x R9 290x in full time mining.
