I like Bitcoin and Monero. Not a member of any cult though. They are freedom tools. Maxis on both sides spread FUD about the other. In the long run I think/hope Bitcoin will get strong privacy features and XMR will go to zero, but for now it is useful.
Discussion
Monero will never go to zero(why are you measuring in dollars?) because if you believe it has a utility value for privacy, there will always be a price above zero.
Until Bitcoin/LN/other layer can provide the level of easy privacy that monero does, it'll have a market value. Bitcoin will always have a massive (and growing) liquidity advantage over XMR tho, as they're competing for different markets
L2 privacy can never be a full replacement for L1 privacy.
L2 sacrifices major aspects of onchain like self-custody, permissionlessness, p2p, final settlement, etc
Monero is already king of privacy coins too. Network effect has too much momentum. You'll have to get users and markets to switch over. Look at Lightning and Liquid. Been around for years already but only a tiny fraction of those businesses and users that accept onchain Bitcoin accept them.
You say you are not a member of any cult but still your bias is pretty noticeable.
Not to attack you but don't you have considered a couple of things.
1. Is hard for XMR to go to 0 if it is being adopted by grey and black markets as superior just for its privacy features, it is private by default, as with Bitcoin you must take an active and costly on time approach, given that even to make 3 mixes of a UTXO on a coinjoin you have to pay pool fees, and it costs time while your UTXO is chosen to go in CJ.
2. Bitcoin hasn't advanced shit given the constant drama with main devs and their agendas, privacy is a serious topic (IMO) for Bitcoin and it should be made a priority, but it seems there are other priorities.
3. If you have seen the process on XMR development, there are basically bounties, this means you vote by donating to initiatives that the community finds important in the first place, it is not a debate by a buch of dweebs that might be getting grants to push narratives on what is currently important.
I agree with all of that. I do think there is an argument for going painstakingly slow implementing new features on Bitcoin. I love and appreciate that Monero has taken more chances and evolved faster, and IMO that has paid off. A major flaw in Bitcoin though could set us back years. That being said, on a long enough timeline (decade plus, maybe?) I do think Bitcoin gets better privacy features and then what edge does XMR have? If not, I could see a future where they coexist forever. Maybe governments and public companies keep their wealth in Bitcoin, but private individuals and companies keep it in Monero. As things develop, it will become easier and easier to swap between the two depending on what is needed for a given situation.
