Also if you look at coinmarketcap and coinlib, you will see different prices. In my opinion it would be better to follow the price of the exchange you use. Because you can see different prices as average and we do not know which one is right.
Actually, there's no right or wrong price.
It all depends on which exchange you are dealing with.
So basically, it relies on the demand and supply of that specific exchange.
It might go lower in a small unknown exchange but you don't know if you can get out that fast and safe.
I would say, better check the bitcoin price on the exchange where you convert it to your fiat money.
