Maybe it was not clear from my first post. I lost my invested BTC, so I warn everybody before buying hashlets again.
?! Your fault?
Have you send your funds to CoinEx?
I sent some btc to my fund on ZenCloud. It was OK. I bought some hashlets after that. It appeared OK to. I received email about activation hashlets. But after refreshing page every purchased hashlets are lost. Where I did fault?
