Taking profit from your Bitcoin investment is not something bad and worth debating since all purpose of investment is basically to get profit at the very end of investing. During this profit taking one should understand a simple terminology like this one, firstly who holds longer makes the best profits, then why collect profits too early if your goal as an investor is to make steady profits with your investment, taking some profits after separate cycles is not bad as per if the need for it occurs.
I can't agree with your statement because long-term investment in Bitcoin is not the only way to get profit. A lot of profit can be earned even by short term investment. Many times it is seen that many people invest in Bitcoin for a short period of time and earn a lot of profit. If you have a large amount of bitcoins you will be able to earn a lot of profit from bitcoins even with short term investments. Let me show you an example how to earn profit by investing large amount of Bitcoin in short term.
We looked at the crypto currency market in September 2023 when the price of Bitcoin was around $25,000 and if you bought 1 Bitcoin it would be twice (2x) what it is today. This clearly shows that this is not a long-term investment but an example of a short-term investment. If you were to invest in the DCA method at the same price at the same time let's say you would have invested $100 per week or month. Then the amount of your invested bitcoins would be 6 x 100 dollars in 6 months i.e. 600 dollars.
So if you have more amount of money then invest more amount of bitcoins and you will be able to earn more profit even if it is a short term investment.
I want to say you are not following DCA method, greed is working inside you and you have not invested. Those who once started investing in the DCA method are depositing their assets in Bitcoins from zero amount. Investing in Bitcoin over a long period of time can accumulate wealth as it is a regular investment. Some invest weekly and some invest monthly (according to their income), long term investment will start their right journey. But you mentioned short term trading here, your idea is wrong because short term trading is more likely for you to lose. It is natural for Bitcoin prices to fluctuate more and more, so investing in the DCA method controls the average price of Bitcoin.
