I've found the easiest way to battle FOMO is not to compare yourself between then and now but more like what you would do if you DID purchase the coins in 2010.

More than likely, you would sell in 2010.2. There would be about 100 price points where your body would say CASH OUT. Markets are all about taking money from the inpatient and giving it to the patient.

I still remember reading about this weird thing called bitcoin on this website around then, I had most of it setup to start mining but got distracted and forgot about it. That is until it hit $100 and I figured 'well it wont get much higher so there's no point now'
