Can you do a pump and dump with little money?in a cryptocurrency
The so called whales are the one who can really have an effect of the movement of the price. Small amount doesn't really affects the value, though if small amounts got combined maybe it will. But the price is really not dependent on anyone, some group might manipulate it for a short period of time but will once againg draw back to its decentralized feature.
Dumping and pumping happens so ussual in the crypto world, I may say that this happens because bitcoin haven't reach yet it stable state. And another thing is that there were still lot of people not engage with it.
