My opinion is that ETH will have another hype very soon. A month after Devcon1 ETH price started a hype and investors had a return of aprox X10.
Now we have this graphical showcase of price:
On this image we can see that consolidation is lasting from mid June 2016 and now turning into ascending triangle formation. In July and August we have a reversal H&S and green volume growing in September, most before and during Devcon2.
After the speculators leave the market (ones that bought ETH before Devcon2 and wanted to earn in day of two because of the event) I believe we will see big impact from Devcon2 on the market in a week or two max. This can be accomplished if market that is not involved in crypto accepts the information from Devcon2, DigixDAO releases 2.0 version of DGX and Augur makes REP distribution over the crowd. All this events are announced soon to be accomplished.
