And storms started, well a little one, its gown down... yo
This has been covered many times before, and it works more or less like that:
Big players use trading bots with small amounts driving the market up or down.
When they need to accumulate, they place sell walls and drive the price down using low volume 20-30% below ATH
This causes flash shake out and instantly buying large amounts from the sell order book, which has been pushed down.
When they pump up, they place buy walls, and drive the price up using low volume.
This causes panic buying and when the buy order book is thick enough, they dump.
Now the difference between Darkcoin and other coins is, that due to the fundamental values, flash dump by pumpers never causes panic selling, price recovers and settles on the higher floor than before.
Rinse and repeat - win-win for everyone except the panic sellers who panic bought.
