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.
As for project development, I didn't notice much development in years. Last thing I remember was added option to exchange RP to free spins
You think so but you never know if you would still make it to accumulate more BTC than what you must be having right now.
Honestly, I did know about freebitco.in back in 2015 and I kinda used it to accumulate my first satoshis too.
Over the time though, I lost track of my satoshis since I forgot the email and password and besides that, I still didn't collect every free roll from the faucet.
It was just too time consuming while I had other things to work on the side. But yeah, the initial satoshis from freebitco.in were surely a blessing.
