In my opinion, it is not a big mistake because, of course, selling somepart BTC and then buying it back when the price drops is possible, but we can only do that if we can accurately predict where the price will go. However, if we can accurately predict the price of BTC by doing that, then we will definitely increase our BTC holdings.

However, for those who are less skilled at predicting, it will certainly make us regret selling BTC. For example, if we sell BTC and the price then rises sharply, we will definitely suffer a loss. The point is that if BTC has been sold, then when it is bought back, it will certainly result in fewer BTC being purchased. So, it depends on whether we can predict well or not.

However, in this case, the decision lies with the BTC owner, as selling part of the BTC is acceptable as long as a profit has been made.
