To clarify DASH pump, see https://poloniex.com/exchange#usdt_dash , click monthly view.
The pump was executed during last 30 days without any huge announcements, the price went up 400% against USD. This approach obviously requires cash and "strong hands" that we do not have here. If done right the distribution on big volume does not hurt so much. This is a common approach in stock exchanges on pink stocks, first accumulation on low volume, then pump.
