It's fine to diversify into Monero. Bitcoin is still the real thing though.
Bitcoin is a Statist's wet dream...traceable and tracking every last transaction. Like tatooing your entire financial history on your forehead for the world to see.
Monero is the real thing. Monero represents liberty, bitcoin is enslavement.
The zerocash functionality can be implemented in Bitcoin at any time after it's proven it's value. Zerocash is better than Monero at any rate.
Ah, but it won't be done for many political reasons.
