I think you are wrong. A lot of people think that Bitcoin will make them rich. That's not necessarily true, Bitcoin might collapse due to for example a critical bug which wouldn't be fixed on time. Most people treat Bitcoin as an investment, every kind of investment is risky. You might lose a lot of money if you continue to be that ignorant. No taxes? I don't know where you live then. You have to pay tax once you cash out. Transactions between BTC addresses are impossible to tax, for now.
