When BC came to El Salvador it was a mess - they had a 1 minute delay feature for people to see price - So was easy for profit takers to use real time arbitrage to make profit - on both selling and buying.
Plus it's full on stupid . You want some of the poorest people in the world to hold their wealth in a Yoyo Ponzi scheme - buy at $60000 , now $30000 - - how you going to afford your seeds to grow , your kids books for school . Poor people don't want a joke , they want certainty .
If was facilitated mainly to reduce bank transfers back from say The USA - a noble cause , other countries like Philippines rely on such money as well.
Why not setup a Bank in The USA or Emirates etc and get commercial settlement rates .
I'm sure most developing countries run USD , Euro accounts anyway to pay for imports. stability etc .
Then give citizens dual currency accounts - with nominal conversion fees
Absolute stupidity
