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.
They are expert doing the business and it's tough to play against this big players, there's a chance that they will unload those coins and wait for the holders to react and once they've seen the target they will buy more. It's a cycle and a battle of mind conditioning, you need to have a good nerve taking the risk and not to fall with this kind of market condition. Assess to make sure you'll get into right timing.
