For me it is bitcoins because as a teen ager it doesn't requires a lot of identity check like IDs or parental concent which I cannot access. And it is much fast and easy to use though rather than paypal. And the fees are not that much compared to others. And it can easily hide my identity. I'm not using it for bad way but I'm just a teen and bitcoins enables me to already access that even if I'm still young. And the most important thing is bitcoin can gives you much profit than paypal. It can also drop but we all know that it will rise again.
