I think bitcoin can help for the future transferring of money in a safe way and in the fast way also in low fee per transaction. Bitcoin have a potential to make more expensive than now because of its being popular and also more users and holders come to use bitcoin. Some of the country make it legal in using payment in different store or any shop.
it is true that blockchain technology is very safe and sophisticated, making cryptocurrency and bitcoin will be suitable payment tools for the future, and to realize all that begins with the acceptance of each state government because until now only a few countries have accepted bitcoin as a means of payment valid other than the national currency.
