It can create something good but you can't just call something can be better bitcoin. Because bitcoin is not good, there are tons of better blockchains than bitcoin but bitcoin is the first, it has brand value and asset value.
Ampleforth is chain agnostic. It can run on anything with smart contracts and they plan to actually run on multiple ones later. So better is a bit general word. What Amplforth can be is better designed as a monetary concept. Forget technicals for a second..the best crypto for mass adoption needs to be stable to be used as a currency and not be correlated to fiat. It aims for a 2019 dollar cpi range. This is a gamechanger. Think of it like this. The cost of your home us 100k ampl and 10 years later it's still worth 100k ampl (all other factors constant) non inflationary money kills the corrupt money system bit is also stable enough to get real mainstream use. No one is gonna use bitcoin as a currency...it isn't gonna happen. For these reasons I think it can go dar beyond Bitcoin could into the mainstream.
