How bitcoin helps for your life?
This your position is actually right but at the same time, what I see is the advantage of using bitcoin because quite a number of people repatriating funds home don't know about bitcoin and the few ones that know might be unwilling to use it due to the fact that they are scared of going against the law in which the position of government is unknown and they could be regarded as money launders. Aside from that, what of the people the money is sent to rather than collecting Fiat immediately, they have to go through the stress of converting to fiat in which the value might even fall within the waiting period.
