Is there really someone who can control the price of bitcoin?
I think we don't need to worry because we still have the same amount of bitcoin even if the price goes down or up.
The problem is, if time comes that you need money in fiat and the price is still very low, you're screwed.
Yes, there is people who can control the price and those are the whales majority from china.
You wouldnt have that problem if you just sell it when you have a feeling that it will go down dont hesitate to sell. Like what I did. Good thing I sold mine around $750 yesterday.
