Investing long term in bitcoin isn't about being courageous or determined. It's about knowing what you want and take it. If you really want to be a successful in life and you see bitcoin investment as your ideal form of investment, then you have to be serious and learn how it works.
Following the rules, and strategy to a successful bitcoin investment is easy. The only difficulty is if you dont have the finance to cover for your basic need, emergency funds and savings before investing some percentage of your discretionary income. And I wont advise such person to start the investment in the first place. They should work on their finance first.
I read somewhere that "it is harder to maintain freedom than to gain it"
Yes, it is true, this also applies to investment.
When a person starts investing, various thoughts start coming to his mind from the beginning, if the price increases, he thinks whether he should sell it now, and if the price starts falling, he thinks whether it is right to hold it.
Wrong decisions are born out of all these thoughts. One wrong decision is enough to break a person's investment portfolio.
Therefore, before investing, a person needs a lot of perseverance, his mind needs to be fixed in such a way that it is possible to maintain the investment portfolio until a specific goal is reached.
