for me it is easy to use and you can get it for free
It is for free if you have a source of it that doesn't require investment. Faucets, working for it just like earning real money, in exchange of your effort you can get what you work. Being decentralized is what I like the best about bitcoin of having no stable price, it is giving us an insight to pump it's price to it's higher possible state.
These days we cannot get bitcoin for free until we give our effort in different way to earn that is possible. In the early days of bitcoin free giveaway was provided which now is not found anywhere, but the earning chances has increased a lot and one can earn good depending on his skills as well investing ability.
