I agree that the exchanges to a horrible job of rolling out new products with almost an entirely "build it and they will come" mentality. I would think the universe of people interested in weather derivatives vs the universe of people interested in bitcoin are night and day, but again Nadex didn't get much interest so maybe not. I'm also not sure that there are many brokers for retail traders to access the weather or insurance futures easily, am I wrong on that?If you had read my post more carefully before replying, you’d realize that I addressed the weather and insurance futures problems as wholly liquidity related in a separate paragraph citing manifold problems with previous futures contracts rollouts.
