Bitcoin price is determined by the few whales who happened to hold since the early days. If they want they can pump BTC to 1M $ and if they want they can dump BTC to 100$.
Doesnt matter who you are, A BTC holder or a daily trader, whales control BTC price.
What I mean by whale? The person who have more than million Bitcoin.
Bitcoin technology is great but Market is compeletly different story.
Yes, this can be manipulated, but for what? Whales get a steady profit from Bitcoin volatility and I am 99% sure that none of the whales will destroy the market. It is not profitable, it will bring loss, therefore it will not happen
Im thinking about this: all bitcoins, assuming that whales want to sell them in large quantities, simply cant be exchanged at exchange offices. There will be panic in the market and exchange offices can suspend their activities. Is there such a possibility? In any case, responding to the post, most likely the whales simply will not be interested to bring everything down.
