No matter how bear the market will be in future, someone who have been investing into bitcoin for three circles and above will be in profits because the bottom line of the dip in every new circle is always higher that the previous. Also, bitcoin creates a new ATH in every new circle.
However, you are not to be withdrawing from your bitcoin portfolio constantly, but once in a while, to avoid selling too many bitcoin too soon and be left with little portfolio so that you don't regret your actions.
Yes, If someone wants to withdraw a large amount of Bitcoin from their investment quickly, their interest in the investment may decrease. Especially when Bitcoin reaches new heights, regret may also work in them. If you can increase your investment patiently, rather than panicking about the temporary bearishness in Bitcoin investment, you can definitely expect big returns in the long run. Everyone who has been able to hold on for the long term, especially the minimum two cycles, has benefited. The supply of 21 million Bitcoin is gradually coming under the control of large investors. And at this time, those who can keep bitcoin as much of their control as possible through holding will benefit in the future. Even if the investment is profitable as expected, if it can be held without withdrawing the entire investment and it is set as a new goal for long-term investment, the amount of profit can increase to a large extent.
