Thread is all over the place.
I can if needed, a bit messy in keeping track of the books to mix up both operations.
I understand the 4.23 BTC transfer haven’t been completed yet awaiting one other signer. I’m on standby to transfer the equivalent of NBT from Bittrex during the next 5 hours. BTC is still a quite jumpy. ($495 at time of writing) 
Re Poloniex, I have already transferred 2000 NBT to FLOT and will transfer the remainder once Poloniex clears my 24h cap in about 5 hours time. Given the discussion I assume @nagalim will then transfer the BTC into the gateway’s Poloniex account. Correct?
