That is the same person that we are talking about,most likely he is an avid gambler too as I said but I am also quite confident that he should have tons of referrals also as his id is really low with just 5 digits.
That is crazy betting though,100 Btc wagered means that he has gambled like 5-10 Bitcoins which is a lot of money and I don't know why they do that,they sure win the daily jackpot or monthly jackpot but those amounts are ridiculous compared to the money they spend and even thinking to get that Lambo win is something that does not guarantees you will in profit so I have a hard time understand their ideas.
If his account ID is only 5 digits it means he is an old player like me but it looks like this person is not only a whale on freebitcoin but maybe has a youtube channel or an author as well which attracts a lot of people to play on freebitcoin so he is getting easy money now from his referral income for a few years, of course it may be because he only plays with free money from that income rather than his own money, I believe he doesn't use his money betting that big

I feel like there are people who end up with a lot of money because they are early investors of bitcoin, and those people tend to like the situation they are in with the money they have and know exactly how they would like to spend it.
If this person wanted to gamble as much as possible without ruining their finances, they knew where they wanted to do it, let's all remember that this is one of the oldest casinos in the crypto world while also being one of the earliest faucets at the same time. Which means it's both famous but also it is so trustworthy that it has been around maybe near a decade and never had any customers faced any troubles. So, where else to spend your time if not here?
