.....I think exchanges link buyers and sellers together in a way people that will buy will buy bitcoin from people that will sell, but certainly this will just let the value of bitcoin not to increase or decrease.
It will not increase or decrease if all sellers and buyers will agree at a fix price for BTC like $55,000 for example.
It will increase if buyers are willing to purchase at $56K and sellers will deviate from the fixed price.
It will decrease if buyers will only buy at $54K and sellers are willing to dispose at that price.
I hope that's clear enough.
The question is, if I sell bitcoin on exchnges, it does not necessarily means someone will buy it, if someone do not buy it but it is sold, that means it will be converted into fiat and the main reason for decrease in bitcoin price during bear market when the price of bitcoin and many others cryptocurrencies are falling?
Uh, no. If you sold bitcoin on and exchange at whatever price and your sell offer ends up executing, then someone bought your bitcoin. Your coins won't be "sold" if no one buys it, because how will it be considered "sold" if no one buys it in the first place?
The exchange is already in all sorts of trouble if your sell order was "sold" without anyone actually buying it hehe. That would a bug that they should fix as quickly as possible.
