some of my friend use faucets to earn BTC but it's to very hard to earn 
anyone here to earn more BTC?
Faucets aren't ideal as a way of earning so don't hope that you can even buy your daily needs through it. Maybe you can start your own faucets and start making your own traffic on it and while you have your own faucet, you can earn through ads faucet claimers. anyone here to earn more BTC? somehow i learn INVESTMENT but it's also hard to me because some person are act like a demon. 
What do you mean by this? by bitcoin and you have an investment already.
