There are a lot of tech stacks already for crypto. I don't think the problem is with the technology. I'm experimenting with monetary policy. I'm making a coin with inflation. I think Bitcoin model, Proof of Work, is good for making decentralized money. So I think building it out of Bitcoin model is a good choice. Another candidate for inflation fork would be Litecoin.
I designed the reward schedule to give early adopters more coins. But some users have asked me about wallet options. That is why I'm doing some research on this topic.
if there is user requests then it makes sense.
as for the coin itself, if all that you are changing is the supply model (supply cap, block rewards, halvings, block intervals,...) then it is not going to be considered a new project. it will be yet another poor copy of bitcoin.
i personally would value a coin that was created from scratch a lot more than a coin that simply copied bitcoin. i am sure others are like this too if you check out bitcoin copies prices! and there is a ton of things in bitcoin that could be changed to improve the result. from small things such as transaction structure and certain encodings (eg. DER for signatures) to more advanced topics such the cryptography (eg. usage of ECC and SHA-2) and scripting language.
We've had a lot of tech innovations. Have you ever asked why tech stack innovations haven't done anything to drive crypto usage? Ethereum was the first major rebuild tech project. It came with a lot of promises. The tech stack innovation list is long: consensus, mining, cryptography, privacy. Recently, there're stacks that promise even more flexibility like Polkadot. There're a lot of experiments. Even within Bitcoin, there're a lot: big block, SegWit, Lightning Network, sidechain.
We're still stuck at speculative phase. We can try tech stack rebuild for the next ten years. Maybe, we'll figure out something. But I think developers are wasting time building solutions to imaginary problems. We have enough technology to solve crypto problems for the next 5-10 years. The problem is in crypto economics. I'm not changing just supply cap and block interval. I want a chain that has inflation as its main feature.
