Thanks for the replies. It's Moonbitcoin, and I was trying to understand the logic behind the awarding of Sats to "members". It seems to be an established faucet, and I assume it is well run and adequately funded, I have no reason to think otherwise. It only reduces my balance for payment by a few points, and it replaces them reasonably quickly. Well all points are awarded desperately slowly, but that seems to be a feature of all faucets as I understand it.
Faucets seem to be a useful way to gain traffic (probably of low value), and I am thinking of creating one for this purpose.
moon bitcoin is trusted faucet it reduces your balance only if you give too much time gap between 2 claims or to when admin adjust average reward .
