I think we need a simple tool to use btc worldwide not like a Visa card but something that even we receive our salaries in different currencies

It would be nice to just buy btc with that and then use that btc to pay services and goods where automatically exchange to the currency where we purchase those goods & services

I think that Eli Rousso with Multi.Vault was very near to achieve this primal tool to just use it contactless as a hard wallet that we use together with your Home keys for exemple
