Is it not already disrupting the global remittance market?
Sending remittances through an intermediary is a costly affair. Very often banks charge a commission which is a huge sum of money in terms of its monetary value. Bitcoin can surely disrupt this entire market with ease. However, more education and awareness is necessary here.
This is one of the reasons why banks do not like Bitcoin at all. Because here you control your own money and you choose what to do with that. So Bitcoin should dominate the financial and global remittance market.
Bitcoin is an alternative to banks especially for the unbanked or the underbanked but Bitcoin does not take all users from banks. There are people who choose banks for their fund transfers and there are people who pick Bitcoin for their fund transactions through Bitcoin blockchain.
It's same with global remittance market, it's opened for banks and Bitcoin as well as alternate cryptocurrencies and other methods. It's not time for Bitcoin to totally replace banks and I have my strong belief that Bitcoin will never completely replace banks nationally or globally. There are options and people have freedom to make choices, so Bitcoin has no power to mandate everyone using it for either personal or business purposes.
