I never intend to leave it all in monero, but, it is more easily private than the hoops I have to jump through for BTC. (Don't you dare tell me lightning solves that, because it doesn't and lightning is trash that's barely useful without way too much custodial nonsense. On chain BTC is way simpler.)

I really do think that XMR is the digital twin of silver to BTC's gold. Besides there's enough space for both and will be for a long while.
