I want to transfer my 1 etherum to bittrex. But after acknowledging that btc-e was charged with money laundering. There is a chance that etherum I have may be laundered/shady. Can I get in trouble by depositing these coins in bittrex ?
P.s note that I have purchased my BTC legally through localbitcoins.com and transferred them to BTC-E for trading purposes.
Well, their main Ethereum wallet was publicly identified, so it is likely possible, in theory, to identify your coins through taint analysis. Having said that, the chances that anything will happen are slim. I don't think anyone cares about your 1 ETH. Their wallet was endlessly split, paid out in refunds, and that money has been disbursed into the economy -- it's long gone in many cases. I don't think law enforcement agencies are instructing exchanges to freeze anyone's accounts; we would have heard about that by now.
I always play it safe, so if it were me, I'd probably send it through a non-KYC service first to get back some clean coins. Just so I would have peace of mind. But like I said, that's probably overkill...
