SNIP
My joke:
with a Balance of 4 BTC and the same operations, could I have got a profit of 14 BTC (4*350%) and be paid for it?
Congratulations on making 350% on your few Satoshis, and I don't think that freebitcoin will be bothered by your winnings even if you would have 4 btc and you make 350% on it too. It had been in this game for a very long time, one of the ever running faucets till date (or IIRC, it's just the one running currently out of the many we had in the beginning of crypto).
10 BTC is a lot right now, now that BTC value have also pumped up, so I am sure that it's going to hurt them a little and I don't think they can see a winning like that at all times given that they only have a limited number of games and then their house edge for it are also higher than the most leading gambling sites nowadays.
Many of us started with this faucet but many of us have also forget it after some time but then realize later on that freebitco is still actively operating so we login on our accounts again. But there might be others who are also an old faucet but they aren't only heavily promoted as freebitco, like for example this one: Yannik.biz (I am not affiliated to here, only to be clear).
