While you are panicking over the decline in the price of bitcoin, the largest bitcoin holders will have an even more volume of bitcoins because of the panickers
No panic here either, I try to make quick investments and hold for long periods, I even have periods where I avoid bitcointalk and most news all together.
Holding has been the key for me, so I keep doing that.
Same, I often avoid bitcoin talk and even news related to bitcoin everytime I'm holding. I want to stay firm regardless of the news so that I can focus on holding because we all know that bitcoins value change overtime either green or red overtime.
