yeah the wager image you provided is a legend website that still survives and has many users or players, imagine how rich the website developer is, at least a gambling website should be like this and can provide many choices or bonuses that can be claimed every hour and provide opportunities for the players to try.
That gambling site still runs until now, and that is normal if they can get that huge money because we know that many gamblers are still playing on that site. We can claim every hour of the free coins if we don't want to gamble, and they allow us to do that. But we can not expect to get big money from that because the reward will adjust to the bitcoin price.
Not only that, they are in the gambling industry for more than 5 years already, they are one of the pioneers here in crypto gambling industry. And look at their ranking and number of visits, you can tell why they are profitable.
https://www.similarweb.com/website/freebitco.in/That makes freebitco.in becoming one of the leaders in online crypto gambling, which still online until now. From that rankings, no wonder if freebitco.in can survive for a long time, and they still have a huge visitor who wants just to claim the faucet, playing gambling, or use their investment side.
When I discover cryptocurrency, freebitco.in was the first website I saw on the google search bar and claimed a lot of bitcoin there. Imagine that I save those BTC last 4 years, maybe I earned a lot of profit on their platform through freerolls. Now that they're very popular and many gamblers are using their site, probably, they're earning millions of money per month. That's how a gambling platform big right now and can't imagine that online gambling platforms will be in the mainstream for many people. The developers are lucky because they gained a lot on creating a crypto gambling platform and it's a brilliant thing to enter the crypto industry.
I remember those years. The years that I earn free satoshi from the freerolls. I remember the reward is about more than 10k satoshi per roll in an hour. That makes me have a chance to make at least 0.001 btc, and I have active referrals, which can give me additional satoshi. I believe they can earn millions of dollars per month because their site has a lot of visitors.
Juniper believes that providers in the online gambling industry, particularly in the casino space, will increasingly offer engaging products to drive user adoption and player spend; Juniper forecasts online gambling users to almost double, reaching 684 million by 2022.

No updates thisnyear but they're already making a sure guess out of it until 2022, or maybe more than that.
That is because we are still facing the same problem now, but I believe that the situation will be changed in the next year or next 2 years, and I am sure their income will be bigger.
