My plan: Hold as much as I can afford to hold long term. When needing cash flow, then aim to sell in lots around 1 year after each halving. Buy back in around DCAing in around 1-1.5 year before each halving.
That is a very good plan and also quite appropriate for you to do as long as you have the ability and a greater level of patience. Because often I see some people who find it very easy to say things like that, but not so easy to do it, especially for the duration of what you said. Sometimes any plan will not go smoothly because there is the influence of temptation which comes naturally to each individual, so that is when their patience begins to be tested well and those who are not patient enough will definitely give up by giving up what they have previously bought.
