This is very interesting but, are you sure that you can apply this metric universally while disregarding all other factors? Amount of users holding a currency may not be the exact correlation between price. For example, it could just be a side product of another variable such as, the amount of merchants that accept a currency as a means of payment which would naturally equate to a wider network
but would not mean that the price is correlated with the network size but rather, the range of use-cases currently available.
Of course it is an overgeneralization. Actual price discovery is much more complicated, and is based off of many factors, such as:
Network Effect, usage, utility, quality of developers, quantity of developers, consensus mechanisms, features, hype, security, fungibility, amount of research at the protocol level by acadamia, emission curve, inflation properties, market/niche, road map, road map feasibility (time constraints and technical), competition, governance, wallet flavors (iOS, Android, Windows, Mac, GUI, light wallets, hardware wallets, etc.), reputation, volume, liquidity, historical performance, transaction capacity, transaction speeds, transaction fees, transaction privacy, metadata privacy.... and that's just off the top of my head.
Spinoffs are the new flavor of the week in cryptoland (first copy and pasta coins, then IPOs, then ICOs... now spinoffs). Just like almost all ALT coins, the value of the majority of them will tend towards zero. The network effect of Bitcoin will reign supreme.
2nd layer technologies and sidechains will be able to do just about everything any altcoin or spinoff can do anyways. By leveraging atomic swaps, Bitcoin can remain the epic store of value that it always has been meanwhile gaining all of the features of any ALT coin.
At the end of the day, spinoffs are simply a tool that scammers can utilize to fleece greater fools. As is being evidenced by the BCH, BTG, and BCD pump and dumps.
