it's a simple rule. just don't panic. seeing the price go down makes me happy as i can buy more coins at lower price levels. people just have to realize that panic sellers are always losing. at some point when the price is going up and they feel good about buying, they end up buying at higher price levels. it's just stupid. keep holding.
the reality is more people including me are not wealthy and we need money to for everyday needs and majority of us dont invest or what ever, when we heard bitcoin the only thing come to our minds is money so in short we dont holdbitcoins and we sell our coins on a weekly basis.
