Why people should use bitcoin, because it is easy to send and receive money from all over the world, no need for iban no need to pay additional fees to the bank so it made our life easier.
using bitcoin is one that can help in finances and needs, otherwise it is easy for the transaction and without any taxes or deductions. I think if everybody knows what bitcoin is and understand it will join it, because it can help the economy and the needs of the day ..
if everyone is aware of it, I think they will all be using bitcoins. each person has their own reasons for using bitcoin. I also use bitcoin because it adds my income. and I think other people also have that potential.
