I sent 0,04BTC to my Poloniex BTC deposit account, and all I get on blockr.io is bellow message
This transaction is unknown.
You might have used wrong transaction hash, or the transaction you're looking for hasn't yet propagated through the network. It can take a while for transactions to get to blockchain nodes.
Note, when transaction is first seen it can be just an unconfirmed transaction. Those transactions are not to be trusted yet, they are not part of the blockchain.
For more info check this page.
If you're sure you have the right transaction hash, you might want to refresh the page.
IS this normal? How long does it take for BTC to get there? Its been half hour and still the same.
