Is the withdrawal automatic or manual? I tried it and found that it is pending and no Tx was created.
Manual. If you were the one from a few seconds ago, did you just make a large deposit to cash out like 1,000 satoshi gathered from the faucet?
Yes, but the purpose was to test the system including the withdrawal process, and not for the tiny 10 bits.
I personally prefer a system with automatic withdrawal rather than manual- feel like my winnings are subjected to approval!
