It is a better strategy taking profits after hodling for 4-5 years of your bitcoin accumulation.
Am really surprised that you are not learning and getting the right knowledge, first of all, you don't sell in your accumulation stage, regardless of what so ever, because it is not logical in anyway.
Secondly, holding for 4-5 year interval, and start taking profit is not investing, you are actually a trader that is selling some of your asset for minimal gains.
Investing by DCA and Discretionary income can help you take off your mind from your bitcoin wallet which ythe only way you can be able to Hodl for long. Instead of spending time and energy trying to convince someone to Hodl for long, same energy should be channeled on letting them understand why they should only invest with discretionary income and best by DCA. By so doing, beginners won't have any reason to withdraw their bitcoin before long.
Then as for this last paragraph, point of correction, investing with your decretionary income doesn't guarantee that you can be able to hold for a very long period of time, because in my own opinion, the are more measures that needs to be in place in other to be able to hold and develop a strong holding hands regardless of anything that arises in the future, which are; having a source of income and an emergency funds that can stand as a shield during an emergency situation that may arise in the future .
Investing with your discretionary income only does not defines your holding ability, it just helps you to keep your eyes off your investment for the time being, it's your source of income, emergency funds and a possible backup fund that determine your ability to hold till any season of your choice.
