This might be true, but it did not work for me. I sent a small amount 0.011 BTC and the system accepted it. Then I tried to send it to my second wallet and then try to get it back, but at this step there is a warning that "something went wrong". So my funds had reminded in the address they provided, so I decided to get it back. At first there was a wrong Private Key, so I thought, sh*t I had been scammed, but then I reloaded the page at the 1st step and there was a correct private key, so I uploaded it in the blockchain.info wallet and indeed received my funds and sent it to my standalone wallet. This is the transaction: https://blockchain.info/address/1FZs5k3GA8Hn4bAyHX5MeW9rCDxbyKNejz
