Thanks for the effort on a new project but I just don't buy it. It's like saying that you don't pollute because you are using an electric car but the electricity for your electric car is produced by a big old diesel engine. You should choose a less energy consuming coin as metronome if you want to call the coin low energy, not just choose bitcoin because is popular.... maybe you know it already and you will change the metronome coin once you gain popularity.....
It's the entirely new structure of the PoW model that is low energy and yes any coin can be used as metronome. But...Bitcoin is the ideal choice for a few reasons but most of all since our coin is a replica of BTC, it has all the positive traits people like and has eliminated the biggest area of criticism. Other points to note for the choice of metro are blockchain security and strength of which no other blockchain can come close yet to being as immutable as BTC. We cannot be having our entire chain come to a stop because of a 51% on our metronome chain and we have repeatedly seen these over and over the last year on a number of large cap coins. It's the sheer volume of Bitcoins hash that makes it secure and in turn ours as well
Another point to take note of is the accomplishment the Devs behind Bitcoin LE have made when it comes to a creating a more eco friendly
PoW protocol. I can't even count how many alternative Proof of "fill in the blank" methods have been invented but every single one of them is either far less secure, extremely unfair for the little guy or heavily weighted to early adopters/devs and friends. The trustless equality of proof of work is something many never thought possible and now that it is it's biggest downfall which was power usage has just been solved... Idk about you but the sheer magnitude of that just gave me a chub
