I am not sure how it will help to pimp bitcoin in anyway! I have used a few VPNs, and I have never seen El-Salvador as a routing address ever. Firstly, is there a VPN available that would route you through a server located in El Salvador?
Secondly, even if companies see that more traffic is coming from this country, how it would help to pump bitcoin? Not making sense! A little more explanation would be nice!
If we all started demanding it there would be a domino effect and most VPN providers would have to have VPN servers in El Salvador, hiring more engineers there and hardware/infrastructure.
Also, worldwide business people would realize that El Salvador is trending in many ways on the internet creating ripple effects in the whole economy.
If El Salvador is seen worldwide as a biz galvanizer it will attract more money than Barak Obama giving a speech...
Sorry, I am a bit short of a better explanation but I think you get the idea. People would say, wait these people are really passionate about El Salvador... And that means money attraction and business galvanization.
