I wonder how popular is bitcoin payment in Uber in 'El Salvador'.
Maybe Uber will integrate bitcoin in their native mobile apps, now that 'El Salvador' made it legal tender.
Sooner or later, Uber will integrate their payment using bitcoin or other coins, especially if they see people's good reaction to the crypto. They will not be late to integrate the payment using crypto, which means they can have crypto and use it for other things such as investment. But before Uber integrating their payment with the crypto, they will wait for a while and check how big the enthusiasm from people to use crypto. Once Uber integrates the payment with crypto, the other local company will start to do the same, and maybe, the growth of the crypto in that country will establish well.
