I do know for a fact, with the source I will keep to myself, but American Dollars are worth more... as they are "collected", that is..certain people pay top dollar in Jamaican for US Bills, the bigger the better.....
this money from ALL over is "funneled" toward a single point, which in turn is added to other "collections", and also is bought at top dollar and I assume it all leaves the Island...........
this is all the US cash that is used on the streets daily, and much comes from the sale of "illegal products".....so a dollar US that you spend will touch
many hands before it leaves the Island, not through normal banking facilities...
