I'm moving my coins out of Bitstamp I was looking for another exchange. I have sent 0.00007 BTC to just test the transaction. I got the address where I want to send coins to from coinbase.com/myAccountName. Apperently this address changes after a while.
I got a mail from Bitstamp to verify my transaction, what I accepted.
You requested to withdraw 0.00007000 bitcoins to address 1Kr8jaHPqEfwd1ZXMh6PHg2fhM5vqCYAQH.
A few minutes after my transaction it was finished on Bitstamp. I copied the address to the blockchain and I saw it was confirmed and verified my the network.
Then I went back to coinbase.com/myAccountName and I saw the address was changed... I never got a mail or a conformation the funds have been transferred on my coinbase account.
I thought Coinbase was doing a lot of effort to make this dummy proof? What did I do wrong? Isn't coinbase.com/myAccountName made to do an easy transfer?
I'm using Bitfinex now, worked great. Very happy with the exchange!
