But isn't it that we have two, distinct, very different use cases here?

One is a long term store of value. Cold storage. Significant percentage of one's savings. Protection from inflation.

On this one, I think Bitcoin clearly wins vs Monero.

Scarcity. Network effect. Market cap. Adoption level.

The other use case, in my view, is a use for daily transactions. Hot wallets. Frequent payments. Fees matter. Speed matters. Privacy matters.

For this, we probably need to compare Monero with Lightning.

On this one, I think the verdict is less evident. I can imagine a scenario where I convert my Bitcoin, small amounts, to Monero, using some non-kyc exchange and using Monero for some transaction where privacy is very important for me, eg to buy a VPN , where I want to make sure the vendor cannot identify me. Does that make sense?

But yes, perhaps equally well or better, I could use Bitcoin for this, with coin joins and lightning, to achieve privacy and speed and low fees. Without a need to convert to a different cryptocurrency...

I think time will tell which one becomes more popular. Today both options are complicated.

My heart is closer to Bitcoin. For sure as a digital gold, probably also for day to day transactions.

One more scenario is also possible. Neither Bitcoin nor Monero becomes widely adopted for a daily use, in our lifetime, and so it will only be a long term store of value, treasury reserve asset.

For this use case, I definitely bet on Bitcoin.
