I think you should stop using the word "invest", and state that it is speculation. Investing in crypto is the purchase of domain names and site building, or the starting of crypto projects. Just buying coins is speculation.
In as much as the crypto currency system is tailored towards establishing a decentralized society, one of its major benefit is that it also serves as invest for now during this adoption stage. Even after it has been fully adopted and become stable, it will always remain an investment and not speculations.
Speculation is just a way of predicting the future of the investment, but does not mean that the system itself depends on speculation. If its not an investment, how come I read somewhere whereby 16 years old boy that invested in bitcoin at an early stage made multi millions of dollars, is that a speculation too?
