Personally I don't think that Monero's technically infinite supply is the issue when it comes to it not being as good a store of value as BTC, since 1) it is known that the supply will grow (not fraudulent/scammy like central bank monies) and 2) the increase is so small spread over so long that for practical purposes, for the user of the currency, it's the same as having a fixed supply.

The biggest differentiator (imo) is that Bitcoin was the genesis of the crypto space, and this will never change. It's like the face of the whole brand, and inside that it's its own unique brand.

I don't think that will ever change, and indeed I am banking on it. Which is why my savings are in BTC, not XMR.

What does bother me is how many otherwise rational people dismiss XMR outright just because it's not BTC!

In the long fight for more freedom, there is more than one tool.
