You can start using faucets or if you have a inicial capital you can invest in ICOs like the DCORP (
https://dcorp.it ) but first you need to understand the cryptocurrencys and learn about the risks and advantages to use it.
Faucets is only better for newbie, not experienced persons. Also in faucets it is slow earning of bitcoin. However, we should search other ways to earn online bitcoin. In my view, bitcointalk is best for online earning of bitcoin, and in secondly do trading, it is time work but when we know how to trade then we start to earn good.
Oh yes. But i think the faucet of altcoins is better to start learning because this faucets give you a bigger value of the alt, and yes, this forum is the best way to get satoshis...
