If you have a lot of resources and have enough money to compensate your needs.. then selling your Bitcoins is not an really option. You should invest with your Bitcoins rather than selling. Just my thoughts. 
it doesn't really matter whether or not you have enough money. smart traders from time to time secure profits to have a better fiat-btc ratio as it will allow them to benefit from the price going lower. at the end of the day every trader is trying to let the number of coins that he has grow. everything else doesn't matter.
