You can buy Bitcoin on exchanges, its subject to wallstreet gamblers and speculation. You can't buy monero on exchanges, at least not any I know of. Because so called regulators see it as a threat. This makes it way more stable, the value actually comes directly from use value. Monero is like cash without a central bank. In the way it actually functions. I'm 100% of the opinion that Bitcoin is money, but that doesn't change the fact that a large number of investment firms and wallstreet gamblers see it differently.
