Most older members are probably emotionally tied to this site since it was best faucet, and it was source of first free BTC to many people.
If I knew about it earlier (in 2015) I would have probably have much more BTC than I have now.
You will never sure about this since freebitco.in has a built-in dice game to attract players to play their faucet earnings and get ticket for lottery for every wager.
I use freebitco.in before I even discover the forum together with moonbitcoin faucet. But I failed to accumulate more Bitcoin because of many temptation for gambling and ponzi investment that time.
It’s easy to become gullible on that early years since I didn’t expect that the price will go this high.
I, too, remember when I knew about Bitcoin and the first free satoshis I collected from FreeBitco. I was quite regularly accumulating bitcoin through these faucets, but I never thought that a vision that bitcoin could be worth over a 100K one day. If I knew that I wouldn't spend it in all these times.
Also, freebitco hourly faucets gave a lot of satoshi a few years back, and it was easy money if anyone collected that free money every hour and never sold it.
