When the market cap of Monero will exceed the marketcap of bitcoin that will be a great day. When shall it happen?
In the beginning I thought alts are secondary to Bitcoin, so can only serve niches that entitle them to at max a few % of marketcap. Bitcoin used to be between 90-95% of total crypto marketcap then.
Some time after I had bought into Monero, I realised that it does everything that Bitcoin does, but better (by being anonymous by design). This lead me to think that normal innovation adoption rules apply, and even if Commodore 64 has 100% of the markets at some point, it can be replaced by IBM PC, or NES, or both, subsequently. For this stage, I even formulated the wealth preservation theorem that stated "if any of the alts reaches 20% of BTC marketcap
for the reason that it is better than BTC, this will cause 2-5% of BTC wealth to move to that alt for wealth preservation/hedging, which will snowball the alt to become 80% instead of 20% (hence trump BTC in market cap).
Now I am unsure if such a mechanism would actually take place, due to so much inertia that has been accumulated in the system. So I am leaning towards peaceful coexistence, which allows multiple coins to live and have higher and lower market caps. The history shows this is not a winner-takes-it-all market, even if I had thought so. The opposite is true: small things grow and die, BTC stays. But BTC does not account for 90-95% of the market cap any more, as the small things have grown faster.
Yes, there is still a scenario that some coin will take over Bitcoin, and the only coin that has realistic chance to do it is Monero. This will likely require a major flaw in Bitcoin first, but it is already suffering from a death by thousand cuts, if we are honest and clear-sighted.
