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.
Any newbie who categorises short-term holding and trading as the same thing has a long way to go as they need to learn the difference and make a decision on which one they want to do and which one will favour them.
As someone more experienced than a newbie in bitcoin investment, you should know that trading is not the right thing for a newbie to adopt because he lacks the knowledge and experience that will help him become successful in it. So saying that a newbie should decide whether to invest in bitcoin for short-term profit or long-term profit is wrong because you know too well that if a newbie invests in bitcoin for short-term profit, he will fail, which might give him the wrong impression about bitcoin. You should have made it clear to a newbie that investing in bitcoin for short-term profit will be of no use or good to him, and he should adopt long-term investment in bitcoin so that in the long run he will become successful with his bitcoin investment, and he should invest in bitcoin with the money he will not be needing for 4-10 years or more, which will allow him not to find it difficult to sort out his daily expenses since he will be using the money that is not allocated to solve anything in his life for 4-10 years or more.
Yeah its correct that this should never be introduce to newbie. But somehow other people turn on other path then select trading because at first provably they think about that it can give them faster result. And usually people learn their lesson in hard way that's why realization comes later on once they lose and think about how unpredictable the market is. Provably after that they would go thinking about hodling is more better than trading.
Although this is unfortunate thing but I guess that's part of expensive lesson that they need to learn from. If a newbie don't want to experience losing and don't try to adapt a risk taker mindset doing trades much better for them to stick on hodling since it will give them convenience and stress free investment, especially if they already know how to handle their emotion.
