Same here, I just transferred a hefty amount of Ether to trade Neo / Antshares. And I wouldn't be surprised if there's some serious market manipulation going on.
And interesting read. I've been witnessing and complaining about these things myself. I think the solution is to use / build some great decentralized exchange cutting the middleman off, that offers the same level of security an "exchange" offers. After all, that was the whole point of blockchain tech. And I would imagine it's not something hard to conceptualize and pull off for the right people, they could perhaps create a proof of stake blockchain where funds are secured and verified by people who have a lot vested in the system.
