Anyways this should serve as a lesson to our country men who are not disciplined enough to resist taking profit at any upsurge they come across, Bitcoin investment is for long-term purpose and their's more to profit in future if only you follow according to the concepts of Bitcoin investment, everyone should emulate Micro Strategy and keep holding and buying more instead of taking profits you could see how much they would've gained in their portfolio if they were more patient enough, Donald Trump even made a statement during his campaign days that upon his return to power, he make U.S the country with the highest Bitcoin reserve and hold for the future that's to say he understands that Bitcoin investment is for long-term goals and not something you invest to take profits over any rise in price.
I think there is something we seems not to understand about investment when it comes to bitcoin or cryptocurrency investment. You can decide to invest for long term while Mr B plans to invest for short term, what matters here is choices the ability to accept the risk associated with the investment that is why people choose the time that is best suitable for them.
I can decide to hold for 8 years which is after 2 circle and I sell off, while others may decide to hold for 4 years and sells off, the thing here is that if they reached their target and the profit they wished on. Yes, before they sold they were also on profits and aren't sold on a lose instead on a profit.
From the look of your statement it may seem as though you're the one who doesn't have a clear understanding about Bitcoin investment and the question is, was Bitcoin investment meant for short-term or long-term? If long-term, then you reconsider your statement and correct yourself cause 4 years interval is not short-term. Well I might be wrong by not checking how long they've held the seized coins but then any investment below 4 to 10 years interval is short-term and latter long-term, so you saying Mr B may decide to hold for short-term is not clear.
