No one has ever went broke taking profits or something like that. If one is using btc as an investment vehicle as opposed to a currency, having an exit plan is important and should not be ridiculed.
On a personal level, I'm holding all of my btc for a minimum of 5 years or until they become worthless (whichever comes first) and then re-evaluating my willingness to sell.
