Watch Bitcoin videos by Andreas Antonopoulos to gain a better understanding of Bitcoin and blockchain technology. Do as much of your own research and reading as you can. As for getting started, I would recommend Coinbase, as this is the easiest and most secure way of putting money into bitcoin at the moment.
it would be nice if you provide a link so that other friends can follow it on the web. like you, i also prefer to use coinbase for bitcoin deposit, because in this way i feel simple.
