I have presented a mechanism that may dethrone Bitcoin without asking the majority, the exact same way as it has always happened during monetary transformations in the history (leaving the majority holding the bag), and the same way as Bitcoin gained its valuation, which you and I are not ashamed to enjoy.
To reiterate, my answer was that your theory against arbitrage and profit taking back to BTC, required both a positive wealth effect on the altcoin and a negative wealth effect on BTC. I don't see that negative wealth effect being viable, because the masses will be buying what the smartmoney is selling. Your avalanche can only occur under two circumstances:
1. Negative wealth effect possible because the influx of the masses into BTC has peaked after 2017 (or the smartmoney shifts to the altcoin before the masses start flooding back into BTC circa 2016 - 2017).
2. Negative wealth effect unnecessary because the altcoin drives a new market of mass adoption that is orthogonal to the one Bitcoin already claims (and will dominate because of Coinbase, Paypal, Circle, Facebook, etc) and this market has no desire/utility to arbitrage to Bitcoin.
Btw, I am aiming for a combination of the two.
