I think not all of us make a better decision especially when we talk about money matters. The pressure "risk" and the financial concerns, as well as the existing problem, may alter the decisions that we have. Thus, we can`t forecast success on investment by merely having profit because it might end up to another bunch of investors to be trapped in an investment and eventually want a scapegoat even if the outcome would be a loss. Significantly, it will give discouragement to the other potential investors.
There is risk when it comes to investment and the people who made money with this market took the risk and invested when the price was really low, the advantage was that it was a new market and everyone who invested knew the risk involved but they tested their luck and reaped the rewards, there is nothing wrong in investing small amount of money in bitcoin whenever there is a correction as the long term will give you the benefit. The people who lost money jumped into it without checking the market and nothing else, it will be a learning lesson for the future.
