I personally perceived freebitcoin only as a faucet when I first learned about this site. I remember freebitcoin had a lot of advertising banners, and I guess this type of advertising was one of the main sources of its income at that time. So the fact that freebitcoin managed to grow from a regular faucet to a gambling site with a multimillion audience is really impressive.
That's actually true, freebitcoin is one of the longest running faucet out here on the crypto market and by far the most successful one. If you're one of the users of freebitcoin way back, you'll know how high the coins they are giving out as it was based on the price of bitcoin. I remember that the highest jackpot was around 1 bitcoin and I'm not sure if anyone was able to receive that.
Anyways, as far as I know, fb has always been a gambling/faucet platform since the multiply dice game has always been there.
