I'll personally never use monero.
Also i'll never openly fight against it.
I simply think bitcoin is generally better.

That said...if anybody likes spending monero for privacy or whatever reasons that's ok, but i don't think there can be such thing as an alliance between the two, only peoples who use it and peoples who don't.

Time will tell pros and cons of each choice


P.s. i'm on the verge of muting the word monero 🤙
