I have a deposit of BTC I sent from Bistamp to Bitfinex that is not showing up. This is the first time I have sent a deposit since you changed your deposit format on the site. I copied and pasted the deposit wallet address from my "trading" account. Afterwards the address changed. Which I thought was weird.
At any rate, the deposit is confirmed on the blockchain, but is not showing up in my account. I have sent an email to support, but I am not crazy about having to wait 24 hours to get my 171 BTC back.
Please advise.
Can you update on your situation? Was it really a virus or was BFX able to resolve the problem? I really hope for you the coins are not gone.
