Hodling is hard work. The sentiment of the market gets to everyone. I can imagine the regret of those who survived the $2-$32 bubble and then sold before the next spike amidst the doom. The threat of failure is always there but as you pass through the boom/bust phases your downside becomes less and less. Im always trying to reinforce the train of thought that the amount of people who have heard of Bitcoin is still relatively small and further those that know more than they hear on the news is even smaller.
