The concept is we have to think that bitcoin is a potential asset to hold in the long term, so that our investment goals are more focused and not thinking about how the market will react. Bitcoin will always have its moments ups and downs over a period of time, so it doesn't really matter how the market reacts once we have established an investment pattern. The problem lies in how knowledgeable we are in investing and most beginners get stuck in market conditions, so they don't try to learn the long term to invest in bitcoin.
Beginners seem to understand how the market works and how bitcoin can give them returns. But many newbies are too afraid to leave the market especially after they have invested, I mean they always monitor the price movement which at a certain moment has changed their investment plan especially when the price actually drops lower. I can say that as one of my personal experiences at beginner, but as I've been here longer and seen how bitcoin works over the long term, my investment plan hasn't changed much. So I think they need time, they need something convincing that in the long term bitcoin can give them returns, that's the experience.
What can be more convincing for them than the price history of Bitcoin? Shouldn't that be enough to convince someone that Bitcoin outperforms its own previous cycles in its next cycle, it has been proved multiple times in the past, so I don't think that people who don't believe in Bitcoin would get convinced only by words if they are not getting convinced by seeing this.
Facts and figures speak louder than words, and if you are a newbie and have doubts, all you need to do is do some research to find out for yourself what is the history of Bitcoin, where it started, how many problems it had to face, and how it reached where it is today by proving everyone wrong.
