I think we will see a bull trap when whales pump the price in anticipation of the BAKKT launch.
Then, they will dump the price and we probably wont see much recovery until March 2019, where we could see a real bull run again.
I won't anticipate a greater pump during the launch but there will be some significant uphill movement.
Dumping won't happen so sooner after the launch either. It would rather be more of a gradual process.
