HI there !
I just want to give my point of view as a newbie:
I first heard about Bitcoin maybe 2 years ago, and I thought it interesting. But when I saw that 1 BTC = 1000 USD, I thought it was too much money for me and I forgot the idea of buying one.
Incidentally, a few weeks ago, I heard about Bitcoin faucet. And... I just tried it. For that I had to create a wallet and I earned my first satoshis.
Faucets really helped me to know a little bit more about how to operate with Bitcoin (how to have a wallet, how to receive a payment).
I tried to know a little bit more about how Bitcoin is working, and I discovered this forum.
So faucet are usefull to join Bitcoin and begin operating with them.
I think I will abandon faucet after making my first deposit of real money (I then will realize that what they give you is almost nothing).
