Honestly speaking the bitcoin market is good as of now with slight improvement and not much dump except one particular dump before week or so which provided further pump, but are these manipulation just to for whales to cash out before the halving and then invest again at a cheaper value to get most profit of out it post halving? Are we going to witness major dump before halving?
There is always an interesting scenario when approaching halving time, we can not predict in detail how big the dumper will occur.
But in the market factor there will definitely be a dumper because to collect interest in buying at lower prices then the big players will profit taking at the top price level.
