walmart are not using crypto. they are just using a database, same as western union/moneygram. so walmart is ripping off those, not bitcoin,
many companies are deciding to not use moneygram/western union and start their own transfer service. amazon, facebook, walmart. they are all trying it.
but one thing is for sure, they are only transfering dollars, which means FIAT licences. which means fee's to cover all of these costs. this should be where all of us show people prime examples of where people can move bitcoin across countries for even less.
the problem is that localbitcoin buyers and sellers do not offer under 1% of 'spot' fee/commission/difference and so bitcoin is not actually that much better. so until average joe can get bitcoin at as close to spot as possible to then offer the person in a different country a cash out value as close to 'spot' price. then there is no point defending bitcoin as a FIAT transfer method.
instead bitcoin needs to be shown off as the bank replacement. where foreigners that work cash-in-hand can ask to be paid in bitcoin. thus bypassing the banking system and also the buying in costs, knowing that they can instantly send funds across the country, or store them for later, or spend them at stores.
if bitcoin wants to compete against greedy money transfer corporations. then greedy localbitcoin traders need to cut their margins. also exchanges need to cut their delays in approving customers. mining pools need to add a decimal to their 'fee's' to make it well under 1c to get into blocks, instead of 5c currently.
