2. Develop a Strong Conviction.
Understand that Bitcoin investment is one of the best investment right now in the world and holding Bitcoin for long term will be more profitable, and always remind yourself that Bitcoin is still growing and selling now means you have lost the future benefit of enjoying the big price.
having a strong conviction is the best way to not sell-- because often people feel doubtful about the investment they make... they have a weak conviction in themselves that the investment they make will not be profitable. having a strong conviction is the best thing for someone to prevent themselves from selling when the situation is not on their side. although having a strong conviction requires a process, if someone is able to have their own conviction and stay focused on the investment they make, they should not sell.
It's a component, not the best way. At the end of the day if you are not managing your finances and portfolio properly, it's more likely that a long-term plan to stay convicted will not be feasible. Good financial planning and money management is key to make conviction possible.
