...don't you think the superior network effect (security, marketability, brand recognition) of BTC will prevent that? It's not always the best which wins.
Also isn't monero scability worse than BTC (ie. more data per transaction to process)? (I know Monero has an adaptative blocksize but that doesn't solve the centralization of nodes problem).
The larger transactions are a constant factor. Constant factors disappear with hardware tech generations. The real scalability bottleneck in bitcoin is political. Monero doesn't have that problem yet.
Bitcoin absolutely has a huge lead in social capital, and it remains to be seen that Monero can match it. I think, however, that financial value and the promise of growth motivated the development of that capital. Monero seems to have more upside potential now, which may cause a hyper-speed catch-up in social capital. Time will tell. I certainly can't put intervals around my guesses on that point right now, so they seem pretty worthless, predictively.
Another point: Old school bitcoin enthusiasts have been easy to sell on Monero from the start, and it is not so easy to ignore among the scamcoin hordes any longer, so I expect a lot of them to get on the bandwagon in the coming 6 months or so. They will bring their network and social capital with them.
