The main reasons I don’t “invest into” Bitcoin, Monero, & Z-Cash are the same reasons I don’t invest into Francs, Yen, Yuan, etc. Is because they’re currencies, imagine if a lot of people starting buying Francs, sane people would say the people buying Francs are insane. I invest into stocks because they grow, and compound. I don’t invest into currencies, I swap my inferior dollars for better currencies like Bitcoin, Monero, Z-cash, and Goldbacks which are more likely to retain their value over time.
