Yes, I think this would be a very good idea. It would be interesting to see whether say all privacy coins are correlated in price. If you wanted to commercialise it you could offer index funds in each sector.
Exactly! I kind of started wondering after I read a bunch of whitepapers and so many claimed to be planning to do the same things. The I was researching small caps and realized that there quite a few that don't really do anything in particular other than offer POS, for instance. I used to trade in the stock exchange and stocks are broken down by sector which is very helpful because quite often certain sectors change rapidly as economics change. I was considering it as maybe something that could give Coinmarketcap a run for it's money.
