There are many types of Bitcoin investors, some invest for long-term holdings, while others invest for short-term holdings. But one thing is true, those who invest in Bitcoin for short term are never able to achieve anything big. On the contrary, they face more losses.
No there's one exception on the text that I bolded.
What about those traders who are successful in trading? I mean they're short-term holders of Bitcoin but they became successful? What about them then? They didn't achieve anything big? Tell that to those successful traders.

every Bitcoin investment should be long-term.

So those who have been patiently holding Bitcoin since then have already reaped double the return on their investment.
You don't have the right to decide for other investors out there. I can invest into Bitcoin, and hold it for mid-term only. At the same time, I can just buy Bitcoin after the halving and sell it immediately if I know that I will get profits from it. I know that Bitcoin is a good long-term investment, but is isn't only good for the long-term. At the end of the day, it will depend on the strategy of the one who's holding it. Well, I agree with what you said though. Those who are patient enough to wait for the bull run are the ones who maximize the profit now. Those who risked, and bought during the bear market are the ones who have the most profits now.
Now another big opportunity is going to come in front of us.

So just Hold bitcoin for long time.
Yes, a big opportunity for me to sell all of my token holdings, and will be patiently waiting for the bear market to happen again.

It's a cycle, and holding assets for years, and not taking the opportunity will lead to regret like what I felt last bull run. Hold Bitcoin for a long time? I might be holding Bitcoin for 4 years at least. When the time is right, I'll sell, and will buy again.

If there's an opportunity, always take it.
