I invested some of my money in bitcoins and I know most of the people here in this forum invested in bitcoin as well. The friends around me and people in my country already have idea what bitcoin is but not a total understanding of it. There's already more and more people everyday noticing bitcoin and that will eventually lead to investing. While the main purpose of bitcoin is to be like a payment instrument, most people do not use bitcoin to purchase goods anymore because of its value, they would rather keep the bitcoin thats why its a very popular investment now.
