That's not their only address. Am I right?
It's been a long time since I last made a withdrawal from freebitco, but as far as I know, it's not that process all withdrawals from a single address.
Someone correct me if I am wrong, please.
The bitcoin adress above is not a typical "withdraw" adress for FBC I think. I checked my withdrawals and found always the same pattern. My last withdrawal as of 2025-04-26 06:20:53 came from adress bc1qj3ve8aytxhj69ffp0xyg5vlecxztagma8xe7p0 (held 0.87199019 BTC). A few dozend payments were sent and the the remaining assets (0.7783789 BTC) went to bc1q8u9l6prmwtkd36lc3qnr43yg4pulwrst06sq3h. From this adress 5 withdrawels were sent an the remaining assets (0.773834 BTC) went to bc1q4v30sr2t299slencul9kc6a0e8zp30m6cmymtl ... and so on.
Seems to me if every payout adress is only used once.
