A couple of years ago, I had a little conversation with our old friend Goomboo. He confirmed some things that I saw happening in the market that are very similar to now.
-Place large bid, just out of reach of all but the deepest pockets.
-Watch as the little guys place bids in front assuming "this guy is for real!" and feel the safety of the wall that surely won't let the price fall too far.
-yank the wall when bid depth is sufficient for today's dose of volatility.
-Dump (called The Hammer for obvious reasons)

This works for the other direction of course. In this case, spike the price up first, then halt the fomo by placing a large-ish ask a little above spot while 'they' accumulate some of the quick buck seekers' sell pressure. "Now the top is in for sure, right?" Nope. "Well who would stick a profit taking wall out in the middle? This must be it!". Little guys sell and watch as the wall is pulled and the next move higher commences. Left in a state of shock and awe, they frantically try to figure out what just happened. "Should I buy back? Right now it's a small loss of coins, but if I don't, and it continues, then it'll be bigger... Fuck it! I'll buy back" This all happens just as the top has been seen and they are now the next gen bag holders.
