It is not necessary for people to tell the truth here about whether they are still holding or have sold their positions. It is enough for them to know even though there is nothing secret.
You're free to give any reason you don't want to answer the questions, but the two questions above don't seem to violate your privacy. The reason you continue to hold doesn't mean you lose your privacy and neither does your decision to sell at the current price. If the question were about how much you hold, you might have the right to withhold the truth due to privacy concerns, but that's not the case with the two questions above.
Someone certainly has their reasons for wanting to hold even though bitcoin has already hit a new ATH. They anticipate better potential and of course, higher prices. But some people have sold to secured profits, and then bought back at a lower price. It's up to them, as asset owners, to do whatever they want.
