It's all genuine, why do I call it genuine, because I have already withdrawn the Bitcoins I got from the freebitxxx fauchet. I have known and played this fauchet since 2015, and I have made 4 withdrawals there. Now I'm still playing it, and so far I haven't made a withdrawal because the results from the current fauchet are very small. It was different in 2015.
Apart from Bitcoin faucet, there were also faucet for Bitcoin and Dogecoin.
Currently it may take a long time to claim Bitcoin from fauchet because we have to collect a lot of Bitcoin first to cover fee transaction
You are right, it was back in 2015 like you said that faucet is worth giving time because then it pays well, but as time goes on it became very small that I presently see it as a waste of time because before one can claim bitcoin from faucet, you must be a patient dog since the transaction fee is something else.
That sounds bad, so we also don't know how much bitcoin they have? including casinos and centralized exchanges also the same? the numbers written on our account are just fake bitcoins? can they use the bitcoins we send them for their needs? As long as there are no major withdrawals on the exchange, no one will know that our bitcoins there have been used. Could that be true?
Exchanges are very funny people because they are always bringing figures that are not in their reach to make people feel that keeping their funds with them is safe, when you will know that it is not true is when that exchange crashes, they wouldn't be able to refund all customers their funds at once. Another way to know is when there is a massive withdrawal from the exchange, you will see that the exchange will now deprive their customers from withdrawing and also place a withdrawal limit on customers so that they wouldn't know the truth.
Same with traditional banks, have you ever thought that what id all the customers withdraw all their funds at once, the bank will never accept many withdrawals and they will put a withdrawal limit. This has happened to me and I need the funds for an urgent purpose. Not your keys not your coins. The moment you deposit to an exchange, your coins becomes a business coins, and not yours anymore, it is only when you have withdrawn it that it becomes your again.
