I think its cryptopia. I had the same problem last week and today i send to deposits and still nothing. Just wait u will get your ETN's on your account. Im wondering if i will switch to nanopool. I have used nanopool for coins like ETH and XMR but im now mining ETN on electroneum.space. Its very unstable but i guess i will not be mining ETN anymore after the ICO wallets get unlocked.
