Anybody who is going into cryptocurrency should choose bitcoin and then focus on a long time investment plan because there is every chance of making profit in the future even though profit is not guaranteed, invest with the amount you can afford to loss.
Just like you said, profit is not guaranteed and most people come into bitcoin investment with the knowledge that they will make high profits from it then they invest little amount and hope that the price will skyrocket to the moon so that they will make enough profits. People needs to focus more on investing more from time to time and increase their portfolio instead of thinking about the profits they can get. Let us even remove the profits that can come along while investing in bitcoin, only the security of your assets is even enough.
And especially in the case of Bitcoin investment, you must maintain a long-term perspective. Whether the price of Bitcoin decreases or increases slightly due to short-term volatility during the investment, you cannot panic if it decreases, and you cannot be greedy for small profits. You cannot delay long-term goals for anything in any way, because you will never achieve great success from such short-term profits, and the risks in such activities are very high, as a result of these, your losses will be greater than your profits, so it is necessary to maintain a long-term perspective if you want to achieve great success.
