Bitcoin holding should last at least 5 to 10 years or longer before you can even think of taking profit, because take profits when your bitcoin investment is not up to 5 years it is not a good holding and even taking profits at early stage of accumulation is also a bad investment unless you are a trader,
5 to 10 years? Who gave that rule? Don't die trying to prove a point to no one; there is no award for best holder.
It is not the duration that matters, but the target you have set for yourself. If you are able to get your target, that is, the profit goal you have set for yourself, before the 5-10 years duration you think is standard @OP, there is no issue with taking some profits for yourself to sort some needs.
