i've noticed you listed united bitcoin.
how do you manage to extract this? as far as i can tell the nice people running it stole everyone's coins and shut the window a month or two ago. i tried all sorts of different ways but in the end it looked like you had to pay them bitcoin to get it out.
as an aside bitcoininterest, whatever that is, is now on bitfinex so i'm gonna use your service to extract it to there when it's ready.
Yes, basically they stole all the coins. There was a very specific window of time you had to move the coins from and back to an address for it to qualify. A total scam. That is why you cannot find any operable wallets on any legitimate exchanges.
