If you invest in Bitcoin for a long time, the chances of profit will certainly increase a lot, but for this you should follow the DCA method to invest in Bitcoin. Then you will definitely be able to profit, if you invest in Bitcoin according to the DCA method, it is definitely possible to maintain your Bitcoin investment for a long time. So far, everyone who has successfully invested in Bitcoin for a long time is currently experiencing profit.
However, Bitcoin investment should be estimated at least up to two halving times (maybe 8 to 12 years or up to 15 years), it is best.You are correct about how reliable holding your bitcoin for a long-term could guarantee higher percentage profits even though it is not all fixed. However, halving is just a stage in the bitcoin cycle which is an event that reduces the rewards by 50 percent of which I don't think halving period is the best time to sell even after holding for a long time. I would only suggest that a person holds through 2 or more bitcoin cycles not having even though halving is also a stage in bitcoin cycles and occurs at the growth phase. Accumulation of bitcoin by DCA could help someone to be self discipline. Choose a good DCA allocation that will be flexible for you and aim at a long time holding.
