A question about your Roobet account though - why did they require those two transactions to confirm before you could withdraw?
Looks like they don't care about how much you are trying to deposit or withdraw, just that everything is settled before you can even take 1 sat out.
However, in order to withdraw or tip, we require that all deposits are confirmed, 1 confirmation for Bitcoin/Litecoin and 3 confirmations for ETH before transferring your funds in order to ensure the deposit has been fully completed and received.
