The investment period varies, such as you can invest short-term or long-term. If you invest for a long time, you will get comparatively higher dividends than short-term investments. So we can invest in Bitcoin for a long time by adopting the (DCA) method which gives us the possibility of getting high dividends in the future.
People usually invest considering their personal needs, achieving some goals, interests. However, keeping some things in mind, just as long-term investments can yield higher dividends, the possibility of losses is also reduced to a large extent compared to short-term investments. For this, you need to understand which holding period is suitable for you and invest.
Investment means long term. If you call short term investment as investment here then you would be slightly wrong. We never look at short term investment as an investment, we consider it as trading. You sound a bit like a trader here.
It would be wrong to say that the purpose of investment is not to earn profit. We never want to do anything without profit. But as you said long term investment yield is higher than short term investment/trading. The main objective of us long term investors to hold investments is to accumulate more amount as well as take some profit. But you are more guaranteed of profit in long term investment. If you are planning to be a long term investor then focus on consistent buying rather than focusing on short term investment/trading and long term investment profits and definitely plan and commit to be long term.
