Ok, good explanation (as far as I can tell). But now my question...if you can just keep forking a whole block chain isn't it just a matter of time until a "better mouse trap is invented" ?
Maybe that has already happened with Bcash ? Ie:Rodger Ver selling BTC , buying Bcash.
What will happen to the price of BTC when the masses just buying the hype of the "first one" discover the "new better one"? What is the price of a 1st generation anything ?
Yes, it's a free and open market of Innovation!
By default! That has always been the case for 9 years already. The strongest and best, with most miners and users will win, and has to be continuously innovative to keep ahead.
Be aware that it was Litecoin which was the first Alt-coin about 5 years ago, and there after several thousands followed, and still today each day a "new" Alt-coin is invented. Most of them die early, but we still have more than 1000 in this space today.
It really isn't that much different to what is happening in the Social-app space. Thousands of Facebook copies around the world, all fighting for the top spot. But as long as Facebook keeps innovating and attracting people, it will be king.
The same with Bitcoin: if it keeps innovating and keeps most Miners, Exchanges, App-builders, and Users. It has nothing to fear from copycats as it was the case with the thousands Alts before.
As investor I keep a close look to which and how many Developers/Innovators are linked to which coin and with what new features they are working, testing and releasing. By far nearly all hotshots are working on Bitcoin or Ethereum.
About Bcash (with no major developer): with all the Bitcoin-money Rodger Ver has as well as his huge marketing efforts. He clearly fails to prop up his coin. Just look at the BTC/BCH chart and see that he hardly can push his coin above 10% of Bitcoins price. And I read somewhere that his blocks in the blockchain are nearly empty, which means no one is really using it at all.
