I live in Miami lol and yes tinder is definitely popular in the US. However, when you travel to SE Asia or Colombia your SMV gets a huge boost do to sexual arbitrage and thus you get way more matches. Then when you go back to your home country your DHV goes back to baseline and you get much less matches. This is probably the main reason so many white guys move to Thailand, they get too addicted to having an endless supply of easy pussy available at a finger tip.
