Awsome topic! I think a great example of the "Coinbase effect" comes as a rumer that Ripple might be listed with them and the price jacks up and then when that rumer is reported to be false comes the crash. It seems to me that they have too much power and I for one am looking forward to them having a little competition in the US market for being the most legitimate Exchange. Competition will bring about more equinimity imo and maybe it will help lower their ginormous fees as well.
