I think your experience in the crypto world is more than enough to make a decision for yourself. whether to sell some, or even sell everything.

but keep in mind, investment here is not just about getting profit. but in my personal opinion it is more about trust in the assets we hold. especially talking about bitcoin which is an asset whose price is more volatile compared to other investments. so it is okay to target to sell when the price reaches 150K or 200K USD as you said.

it would be even better if 20% of your bitcoin assets that are sold, are returned to investments with safer and more stable fluctuations such as gold or the stock market.
