2: Dont gamble or invest in HYIP site.
3: Use faucets to collect "dust" for transaction fees - check out FreeBitco.in or Weekend Bitcoin and ... my site, BitRevenues.
Faucet is really bad idea, it's better to spend more time on signature campaign or join giveaway on Games and rounds section, since you could earn more bitcoin.
Sell your skill on freelancer sites which accept bitcoin is also good option
No faucets are good if you believe in bitcoin's future. If you get some 500 satoshit today, it may worth some 1$ in 5 years.
But, if join signature campaign & giveaway & get about 0.1BTC, it may worth $1000 in future
That's why i say faucet is bad idea because you could earn more by join signature campaign & giveaway
Yes faucets also good way of earning bitcoin if bitcoin prices go up.
Most faucets your talking about dust as payments. Even if bitcoin goes up... unless it really hits the moon those payments worth cents are not just going to be worth a ton.
I would not count on faucets for a good way to invest time and bring in coins. You will get cents per hour most likely... even if btc doubles that is a small amount still.
