I think you're on to something here. I was doing some brainstorming just last night and had the idea to monitor the exchange accounts for large changes in incoming transaction volume, with big increases in a short amount of time indicating that someone is likely getting ready to dump a bunch of coins. This would be done programmatically of course. DM me @deelawn on coinfund slack if you'd be interested in collaborating.
Is there a correlation between big token moves and big price movements?
Front running a massive purchase/sell would be great; I've read Flash Boys and saw the effects of this.
Will be interesting to see this play out in crypto. Will dark pools become popular?
I just put a little ETH into Rialto.ai to take advantage of their arbitrage and market making plan; I think they're the best bet going forward. I'd be happy to follow your efforts as well.
I also invested a bit into Rialto for the same reasons. I don't see many good reasons why someone would move a large quantity of tokens to an exchange if they don't plan to sell. It's possible they could be using it as collateral for short positions or loaning it out on Poloniex, but a sale seems far more likely. I'm going to write a script to monitor such moves and their results in the coming months. I'll make a post with my findings.
