Immediately it is a new ATH I am taking profits straight up
If you planned on taking a profit at the new ATH you should have a good exit strategy to take your profit, implying this kind of strategy below would save you from taking a profit way too soon than supposed, I know how the feelings use to be when you exit the market early, and in some occasions, the market moves up like 2x from your point of exit, I suggest you should try this method while the market has not changed direction, 1st take 25%, 2nd 30%, 3rd 50%, 4th 70% and finally 100% 0f your portfolio.
When it comes to taking profits, the saddest experience is taking the profits too soon, I have experience this last week when bitcoin reached 27k+ I quickly took off some profits and within the next few hours, bitcoin raised to almost 30k and there after a few days Bitcoin touched 31k+ severally and that gave me a lot of bad feelings that hard I known I should have waited a little before taking such steps in taking profits too early.
But would you be upset if bitcoin decreased after you sold it? Bitcoin's rise or fall is unpredictable, so there is no need to be sad when we decide to sell it. As long as it hits your target and makes you profitable, then why be disappointed? Greed plus regret is very easy to make you make mistakes and pay the price in investing, instead, you should have a plan and specific goals for your investment, and be grateful, then life becomes better and more comfortable. Moreover, as long as bitcoin continues to exist, opportunities will always come our way, so there is no reason to regret our decision.
