While I wish you were right, but this isn't my experience on the ground.
  1. The government made the decision a good 2-3 years ago. The 'boost' already happened. It had little to no impact. It's not new in El Salvador anymore, and most locals still don't care.
  2. a tiny minority of Salvadorans pay attention to or care about what's happening 'around the world'. The vast majority have no interest in what the world thinks about 'cryptocurrency'. I'm saying this based on conversations I've had with locals, in multiple states - coastal, internal, urban and rural.
  3. not a single human in el Salvador, foreign or local, has mentioned UX/UI or 'confusing tech' as a reason for not using it. They simply don't see a need for it, outside of cheap remittances. The economy is dollarized - This isn't Argentina, Lebanon or Venezuela.
I'm short, the problem is that most people don't see a problem, they have dollars and are happy with them. The issues of diminishing purchasing power, corrupted money, inflation etc are all a long way from the average Salvadoran's mind. Until that changes, which I don't believe it will any time soon, Bitcoin will remain a folly, accepted by a tiny handful of businesses, providing 'Bitcoin Disneyland' to wishful gueros (like me) who are looking to spend their Bitcoin in order to confirm their motivated reasoning.
