Crypto is decentralized, making it a much different concept than a market such as the one seen on the NYSE. This means no central control over the currencies makes the insiders not have a majority of the shares, unless they were to buy just as you and I would (given the crypto is truly a decentralized one rather than a centralized pre-mined currency such as Ripple). So with this being said, it isn't going to be more efficient than the stock market based on the theory stated in my article.
