Long term investment is the best because it gives you time to be able to learn, invest and grow your investment into a certain height rather than you are buying and selling to buy back again, putting you at risk of running at loss. when you make the wrong moves. Long term investment also lowers the risk in bitcoin investment because the longer the timeline of your investment with size, the higher the risk reduces. This is because from history, it has shown that bitcoin price dip bottom line is always lower than the next circle dip bottom line.
Lastly, there is what is called compound interest(profit), this is the same for bitcoin and this is where long-term investors are happy that they started their bitcoin journey early when the price of bitcoin was $500 and imagine that they are still hodling those bitcoins till now. If you buy $10,000 worth of bitcoin at $2,000 per bitcoin and after 4yrs bitcoin price increases to $4000 per bitcoin, it means that the price doubled and your bitcoin worth will increase to $20,000, which means that you have an additional $10,000 profit and if you don't sell and hodli for another 4yrs, your $20,000 worth of bitcoin investment will have yield a profit of $20,000 based on the percentage price increments for on bitcoin.
If it happens that you buy and sell at every circle, you will be lacking behind in your bitcoin portfolio size and you will make very little profit from each circle compared to the person that will hodli for 8yrs and above. Bitcoin long term investors are building their piling up their profit to reap from it in future when it has compounded to an amount that can change your standard of living and turn your life around. This is why we need to live and invest for the future and not to be after what profit that we will make today with bitcoin.
I quite agree with you because the highest bitcoin beneficiaries are those who have engaged in long term investment, those who buy and sell after a cycle are more like traders who monitor for slight increase in price, sell off and get immediate gains, and during the next cycle, they buy at a price possibly higher that what they bought at previous cycle, wait for short periods again and collect immediate gains and move on, and so the cycle continues for them. For me, that's the evidence of short sightedness on the part of those kind of investors, it surely depicts low trust on the performance of bitcoin which have proved itself a good choice over the years with respect to appreciation in value.
Let's take for example, the guy who bought bitcoin when it was $2k and sold off when it reached $4k. during the next halving cycle, he possibly goes to buy at $5k and possibly sells at $8k isn't doing himself much good.
This can even be likened to ordinary mathematics, those that buy for short periods are taking occasional simple interests because their interested stops when they sell, but those that buys and holds for long are on compound interest schedule. As the prices increase over the years, so do their interested compound and their gains turns massive.
Every investor should shun the present gains and temptations to cashout and look far to the long term benefits of holding bitcoin and not just gambling with it, Short term investors are nothing but gamblers and gambling is not a good attitude for a good investor.
