I live in a third world country (Colombia) and the scammy hype is even here, people at cafes telling each other to "invest" in BTC and the other crypto currencies, usually through a middlemen (the ones doing the convincing, so they take a commission one way or another); usually involving people with not much money to begin with, just hungry for an opportunity to make some, willing to take bank credits or other forms of debt in order to "invest". It's all so lame.
