This is just like using credit cards filled with bitcoin, a centralised agency will have to take care of the payments, defeating the purpose of bitcoin in the first place lol.
no, bitcoin life savings should be self managed. in cold stores of the owner. but daily spend amounts wold be used in third party services for convenience, benefits and features that cold stores do not allow.
much like banks store life savings but crdit cards offer features for daily spends
much like share holders store large amounts of shares as certificates and only play with small amounts on trading platforms
much like many people store 90% of bitcoins cold store and only risk 10% (well they should do) on bitcoin exchanges.
people will learn putting all their wealth into a third party service is stupid. this is why rich people own gold, expensive real estate, antique art, etc. because they do not trust third party services to store all their wealth, but will happily use third party services for daily/weekly spend amounts.
