Of course the best time to enter the market is when prices are below, but the problem here is we don't even know what will happen to the next market. That way we need a lot of information and research and we must always be ready with every risk that will face us.
I think you can at least see where the market's next position simply by reading news, updates, development, partnership of a certain coin. It is obvious that whenever there is a huge development such as platform launching, masternode implementation, partnership with huge company, the price react. So with that in mind, we are able to have an idea on the next market position, thus, enabling us to act what we think is the right approach. One example of which is buying and holding until the big news happen. With that, there is a huge possibility that our holdings will take a huge profit when we sell them.
Crypto investment is still a high-risk game, especially when the market has entered a period of high uncertainty and volatility.
It is a high risk but very high reward game and the market is always volatile, the uncetainty depends on our decision on what crypto to buy. That is why a deep research on the fundamentals of every coins we are interested is a must.
