Pardon me for overthinking, but as this is the 1st post of the OP with the included link, I assume that this website was either owned by him or was hired to do link building on his behalf.

Regardless of the reason, predictions are predictions. Assumptions are assumptions.

We just simply do not know if it’s really going to happen or not. I could be right or wrong though. The real answer is to wait for 8 years and see if El Salvador will indeed going to be what the OP says.
