How do I earn 0.1 bitcoins? I'm a green hand.
Making 0.1 BTC is almost impossible right now. The only thing you can do is to trade with Altcoins to get that outcome. However, trading with Altcoins means, that you have to invest something before you can try to earn some BTC. With trading there is also the possobility that you loose all your money.
If you want to make some BTC without investing your own money you can do faucets or playing games instead.
This will not make you rich of course but at least it’s something to start with. Also, if you made some Bitcoins that way, you can go on and start trading with them to increase your profit.
