You will not find a perfect plan that works for everyone, so each of us must have his own plan based on his circumstances, investment plan, taxes, age, social and economic status, and the younger you are, the better it is to leave some Bitcoin untouched for +10 years.
The best plan, in my opinion, is to sell 50%-70% of what you own at a price of $140,000 to $180,000 and then buy again at a price of $70,000 to $80,000.
