Well, this is his first tweet about AMHI (I've never heard of this guy, but yeah if he does have 1000 followers that could cause a jump):
I would like to direct everyone's attention to AMHI. Watch $AMHI run. Watch AMHI touch the sky. about 9 hours ago via TweetDeck
The thing is though, that if you look at the time stamp (about 9 hours ago), since I don't know the exact time of that tweet. I have a feeling it came right after the initial jump and it set of his radar. The huge PPS jump took place a little after 11:30 am and about 9 hours from now (it's 8:30 pm) could either mean 1. that he saw it jump and then tweeted about it or 2. he's just awesome and predicted the jump right before his tweet. I would like to think the first option is what happened, but I'm not sure.
EDIT!!!!
After reading a follow up tweet, I'm going to say that he sent his message out after the jump:
AMHI...may have been too quick for even Twitter. I said it was going to be very quick. Too quick. Only minimal profit. keep watching.
It jumped over 200% today and that is not "minimal" by any means, which means he must have pumped it after the spike and still made a little profit
