The best thing for people to understand is that just because you invest in bitcoin and it makes you happy doesn't mean you won't lose money at some point. As someone who has found success with bitcoin, you must keep in mind that not every day is happy; you can lose money when the price is low and make money when the price is high. However, as an investor, one thing you should keep in mind is planning; don't think that bitcoin has a fixed value. Putting all of your money into one particular investment or line of business is extremely risky, and a prudent individual with a strategy would never do so.
This truly happened to the new forum member because they constantly feel greedy whenever they hear about bitcoin and how the profit comes when the market moves in the right direction. They rarely inquire as to how long it will take or whether the price of bitcoin has fallen at any point. Even if the price of bitcoin didn't constantly plunge, you shouldn't put all of your savings into one investment because you might have other expenses or financial problems that need to be taken care of that you won't be able to afford.
