Can anyone help?  I'm trying to do a small ICO exchange sending XCR from Poloniex.  First I got an error saying the return address is invalid.  If I understand correctly, I must initialize the Poloniex address by sending it some XCR.  So I thought I would send some XCR to my empty Crypti wallet so I could send it back to myself at Poloniex.  But the Poloniex withdrawal has been saying PENDING for about an hour now.  I asked Poloniex if they were aware of a problem with XCR withdrawals and they said maybe there's a problem with the blockchain.  Can anyone offer some guidance?  Thanks in advance.
