For me, bitcoin can change something not everything. Bitcoin can change something especially in economy people can have a chance to earn money even a jobless man. It can help them to build their dream because of the money that they can earn. Bitcoin is a big help in finance. In the other side, bitcoin can also help people in the way of transferring money in any point of the world with a less fee. The chance to buy things without going out to your house and the payment is thru bitcoin.
