I deposited BTC to my Kraken account from a cold storage wallet. I intended to only send to Kraken what I wanted to sell but mistakingly sent all that was in the wallet. I have been trying to withdraw back what I didn't sell. I tried a small amount first to make sure it would work alright as I had never done this before so I sent 0.00099 btc to my original non-kraken wallet, but now an hour later it is still not showing on the blockchain....I know it may not have confirmed in the hour but surely it should have appeared immediately as a transaction on the blockchain? Anyone have any idea what could be wrong? TIA.
