I'm a week into this whole bitcoin thing so be easy on me. I wonder why you would ever sell a BTC ... For example: you buy 100 dollars worth of BTC but the price drops drastically. Why would you sell it when its that low? You KNOW it's going to go up again. You could wait a month (for example), the price will be up again. Or am i totally wrong here?
Everyone must have different needs, so I think they sell Bitcoin when the price goes down maybe they need a sudden need. for that they sell Bitcoin they have.
