Bitcoin is just like any casino or lottery - it is a tax on stupid people who fundamentally do not understand that this is a game they will lose. It is tax on low intelligence.
My guess is that your negative attitude to Bitcoin came from the fact that you bought it during the price bubble and now price drops..? Am I right?
Bitcoin, of course, is not a tax or lottery. It is a technology that will revolutionize the financial market. However, it looks like you need more time to understand this ..
