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 are not really a way to earn bitcoins, when you calculate on the end of the month how much satoshi you have earned you will see that you didn't earn much but you wasted a lots of time.
but before they starting with trade, they need to understan how a transation works, the tx of a transation, how to secure their wallets and etc, and the faucets is a good way to START learning about.
They are good way to start learning how to waste time, whoever tell different is fulling himself and doesn't know or don't want to do simple math.
People are not stupid, if you explain to them how to send bitcoins they will learn.
but the explanation is 100% diferent of the experience, in the major of the peoples starting with bitcoin, they had searched first, but they still dont understand the problems like the late in the transations, and they ask in this forum about the problem after the problems occurred, with satoshis they can make wrong and learn how to repair the problem after he waste his money.
