I agree with you that holding is the most important thing in Bitcoin investment however not short term holding or trading but long term holding if we master the act of long term holding we will become successful investors, the reason why I decided to make it clear is because of newbies if one just say holding some set of newbie may think about short term holding or trading and which is very risky.
The only way to reduce the risk of losing in Bitcoin investment as an investor is by engaging in long term Bitcoin investment, holding your Bitcoin for long will help you relax and stop panicking, those who are into Long term holding Bitcoin volatility won't be something they should be afraid of because the longer you hold Bitcoin the more successful you may become.
We all know that holding is not an easy and peazy journey to embark on. When the price of Bitcoin tend to go down a little most investors are tempted to sell hoping to get some profits. The best thing to do is to train ourselves; first to be consistent to accumulate and to be patient to hodl. One way to do this is to create an understanding as well as a conviction that Bitcoin will go up in the future, these believes will help us stand firm to our investment. Even when we feel tempted to tamper our investment or sell we can rely on our believe because that is the only thing that can help keep us going. Life challenges will come, family unexpected needs like healthcare and possible demise of any close one. These things can be so pressing that an investor may start thinking of investment to be the only way out.
I don't think this is correct, because you don't know about all the investors history. But while everyone can start out at a loss, many investors are new so it's normal to lose. But the probability of bitcoin investment loss is very low, if you observe you can definitely see many gamblers who have been holding for a long time are definitely successful. Investors who follow the advice in this thread will have very little chance of losing. Bitcoin is the only long-term investment that is key to its success.
Investors who will be successful in their investment will be based on the fact that they understand and believe on Bitcoin especially those who have hard experience or heard about previous events (how Bitcoin came from nothing to what it is now). Whatever is being discussed in this thread, not everyone who learn and apply the approach. In as much as it is very helpful and educative its not a criteria that participant of this thread will be successful. They will only be successful in their investment if they go about their investment the right way, at least practicing most of the things we have discussed here especially the DCA method and long term goals. Which has been very useful.
