my guess would be to try and cause a pump, and then when it gets to a certain value then that person dumps, make a quick buck. The guys doing that are also most likely the guys that have 1000s of bitcoin that they can just throw 1 at the new coin and hope for a hit.
hi mate, not sure if this could be the reason because none of these coins pumped after this. also its not like someone is buying 1:1 for the coin,
