When people are dealing and transacting online, it is a good advised to used bitcoin. It is safe,near to anonymous and very convenient.Also it is easy to convert to fiat and en-cash it.Aside from that, it is already legal to used in some countries as a legal tender.
I agree, bitcoin was first created for the soul purpose of making online transactions much safer than they are, because if you look at the PayPal accounts they are easy to hack since they are linked to emails, I mean so many people have their accounts hacked, but with bitcoin you balance is always safe, so using bitcoin may improve the quality of life for people who especially use online shopping a lot.
