With the halving approaching, it is probably better to wait to sell. Usually the price rises leading up to the halving and then there is a small correction before another increase. If you want to sell, you could right at the halving and buy back at the correction and potentially make some profit.
Very true, if you have big doubts about the price reduction you should sell some tokens that you have to avoid the bad things that will happen later.
You should not be in doubt when you are investing, the price would not be reduced in future it will grow more. This happens only when you have not enough knowledge about the market or you are believing over speculations or rumors spread by the haters. If you want to enter in a safe zone make an alternative plan for yourself so that your level of risk decreases.
This is very helpful to calm people who are panicked by the current state of the market but that is indeed what is happening at the moment.
