I don't see this as permanent solution because remittance company has to have money available in every branch office. The issue is how do you cash your money from the bank? You can send steem anywhere anytime, but you will always have to cash the money yourself either by using exchange or a bank. The future will not need remittance. Once you can use crypto debit card to withdraw money with small fee then the world will be all crypto connected.
