I have also quite similar idea and for this idea I am looking also around for about a week.
I was more looking into a coin that could go maybe 1000x. But at the moment trust issues are there as creating a coin is very easy and dumping for about 50k can be very lucrative.
Energy and transaction efficient coins could take a step more. As I understand NANO is good in this, but there are more, which is leading I do not know.
Community and hype are important.
