As far as Bitcoin is concerned, i believe that there are still better opportunities yet to come, and that is why buying of Bitcoin is always repeated in this forum day by day, since an investors can't afford to predict exactly what Bitcoin price will be in futures to come, we should continue buying so that we can't be able to miss out any market opportunities, as an investors that has made up his mind to deal with any outcomes that might happen during your time of holding your bitcion in a long term investment, such investors will not be having that kind of mindset, that Bitcoin opportunities is gone already, but to keep his focus more on how to deal with his long term journey without pulling out his investment in the halfway because every investors knew that most of the investors pulled out their investments, failed to put those necessary thing (emergency fund) that could keep his Bitcoin journey smoothly without touching it.
There is always an opportunity in Bitcoin. If someone regrets not being able to buy Bitcoin at a low price in the past, it will not be of any use. But if there is extra money now, then you can start investing with it. If you wait for the price to decrease like the past, you will see that the investment has not been started.
And those who start investing with a long-time holding mentality have a higher chance of success. Therefore, it is important to keep a long-time holding mindset in investing. There are many people who sell their holdings intentionally or forcefully during investment, which is the main reason for the loss in investing in Bitcoin.
