As long as you're going to sell your bitcoin at some point and it remains that bitcoin will continue to grow into new ATH, this reality is what every investor will eventually experience and There's nothing wrong when you sell your bitcoin because you feel you're at a profit or that you've held long enough to have reached the goal you've set for yourself.

Some persons starting buying at the price of $50k and did so with the intention that once bitcoin gets to $100k, they were going to sell off Thier holding. If they sell at that point and in the next five years bitcoin price gets to $150k, does that mean they should regret Thier actions? Not at all? It's about setting a plan and being through to yourself while you're following that plan. For government and big institutions and whales that have the means of coming in and exiting at the time they want, they can literally afford to stay till they are at a slight percentage of profit and still be more profitable than those that will stay invested for years. It's about the difference in capital.
