For example with the last dip to 6k it is said that the whale was selling huge amounts of bitcoin, which made it go down. Alright, but if he sold it, doesn't it mean that someone else just hold it now?
Not necessarily. If they dump them at an exchange, exchanges will have a surplus of circulating Bitcoins, making the price drop. They're not considered to be "held" by anyone because they're constantly on the selling block.
This is where demand plays its part. There are lots of coins up for sale, and there's more people selling than buying, so the effective "amount" you're speaking of is actually
increasing. You need to look at the amount of circulating coins rather than the total supply.
So it means that if everybody is selling, the exchange is having an overstock of the coin, making the price drop?
I see the point with the total supply and actual amount of coin curculating on the market. Thanks
