I honor that you have some opinion that is not mainstream. However, while you use the right arguments, you use them for the wrong side. If you buy apple shares, you are not buying something that does have a value. At least not the one everyone claims it does have. There are way better producer on the market doing a better performance. You're also investing in the people behind, the infrastructure they have, maybe even the "believe" of people in getting a superior product.
Nothing else is what you do, when you invest in bitcoins. Its not a product, its an idea that is used to get access to other block chain technologies. And it does have draw backs for sure. But it is widely accepted solution for most people.
