Am already doing this but the developers seem oblivious in certain ways. Like they told me the bitcoin code was changed and can only be mined by asic mining chips. So, considering I want it to be minable by average members of the public at the beginning, they’re totally off-base and I paid a lot of money and it’s very troubling.
From what I know, Bitcoin as it is, if you start it anew, can probably be mined by everybody... for a short while. Then one ASIC miner comes in and only ASICs will be able to mine it.
If you make it ASIC resistant, then you need a different algo, maybe RandX.
Maybe you (actually the devs you pay) can do some tricks and allow some kind of mix. But every time, the ones that can mine it cheaper, will mine it cheaper.
And yes, smartphones. That's a different story. The ARM CPU of a smartphone is not the best for mining. It would drain battery very fast, would heat up,... all the things the phone users hate.
So a lot of effort and money for no use. PS. If you think of the smartphone coins, those are not mined, that's not POW. Those' mining is actually some sort of airdrop. That's something else.
My conclusion is that you don't know a lot of things and because of this you are asking for unrealistic tasks, for which they ask unrealistic amounts of money and may not implement much (because the requirements may also change continuously)/
...And you want all this in a coin you'd for from Bitcoin. Why not a different altcoin, beats me.
However, it will be something completely new. An altcoin obviously. And, like the altcoins I know, it will become really challenging to become valuable.
