There is a huge market for this as Western Union is taking a huge cut out of the funds sent right now by migrant workers.
Yes - they take an *obscene* amount of fees from migrant workers (often as high as 30-50% when you are talking small value transfers).
all these 'banks' and their ponzi schemes make it impossible to start a new bank according their regulations
sue you need to be legal, have good record etc but even someone like Richard Branson couldn't open one in UK
he had to buy an existing failed one
people like WU have a monopoly really, on remittances, for now
but they have been so greedy
any new remittance service for bitcoin or any other crypto would have the initial age old problems.
the app is the easy bit, having the way to buy the crypto and sell it for fiat, which most migrants and those they send to , family, is the tricky bit
still having to use banks, and many are unbanked
so, with 'law enforcement' etc. using entrapment etc. on local bitcoins it is scaring people off using
and really, local bitcoins is bigger in places like US
the places where it's really needed, eastern europe, africa etc doesn't really have a footprint
I think for this to get momentum, it will rely on street traders. the currency changers that are found everywhere you go where they are most trustworthy and cheaper than the banks. ever travel to Ukraine, Myanmar, Thailand, wherever
so if they have apps are are happy to cash out bitcoins when someone sending to them stood next to them this is a way
it's down to whether this is how things move forward
otherwise any app that wants to be a remittance service would need to have some office in these countries, lots of expense, jump through all the leagl hurdles, plus be happy to hold the crypto if price slumps after trading, again, they can use the crypto they hold to trade
