However, while investing in Bitcoin must be experienced, you can't invest at any point in time. But if you have experience with Bitcoin then you can definitely invest by following DCA method and accumulate it for a long time and sell it again.
I think a beginner should know the basic knowledge about bitcoin investment and grow his investment portfolio by buying bitcoins regularly using DCA method. Even if many people have no initial investment experience, by using DCA to buy Bitcoins on a weekly or monthly basis, they will gradually increase their investment experience as well as their investment.
But the point of selling is not clear enough to me, because I will accumulate bitcoin first and keep it for a long time. Later I can sell it when my situation and benefits reach the maximum value. Patience is the most important thing to do with this, because if you lose patience, your investment will not last.
We all want to buy low and sell high but unfortunately are not able to do it at the right time. Many times we are tempted to invest and even lose control over our emotions which results in us selling the investment before reaching our specific goals. If we are not able to make a profit by accumulating bitcoins little by little then maybe our investment is not worth it.
