Money remittance is where we should focus on. I think this is an area where bitcoin has the advantage but we never fully utilize or capitalize on it. Imagine having the fund reached the other party almost instantly and with the low fee. For an annual 50 billion market worth, half of that amount would easily change everything.
Totally agreeable, this is a big benefit to especially migrant workers from abroad who often send money several times within one year; a lot of services available charge up to typically 10% or so of the transferred amount as commission. There have been cases in which people have been misled to trust organizations that either overcharge or just have their money taken away. I think this is something that they can trust highly knowing that their money can safely and quickly reach their families.
