Stupids, if they sold it, someone bought it too..
When price goes up, people say, someone bought thousands of bitcoins so price went high
Stupids, they bought it because someone sold them..
Now tell me why price goes up down.
If there are more eager sellers than buyers, the sellers will lower their ask prices in order to entice buyers to buy. The price goes down.
If there are more eager buyers than sellers, the buyers raise their bid prices in order to entice sellers to sell. The price goes up.
I think the key word here is "eager".
