If you hold that long then that was commendable because it is nearly impossible for anyone who will hold that long because when day saw Bitcoin reaching around $10k they might probably sell already. Upon holding there's a limit because it is always not working on our side. I mean you might be seeing a good price right now like $29k at this point and still growing but we never knew when this will end thus why having a target point sell or goal is highly recommended, you don't want to miss the opportunity. Holding was not bad in fact its a good strategy and I've been using it but you should when to have your exit.
