Yeah even though people have this way, it isn't restricted to Bitcoin Investment. How many times have we heard instances where people invested in other sectors like shares of companies and sometimes after the company closes down and you lost all your investment, this I have witnessed first hand so, people still lack the will to look and research what is in front of them and will always want to play safe however once they really understand what Bitcoin is, then they will have a second thought.
There are also such cases when a some one lost money investing in stocks or real estate, then based on his negative experience, he will no longer invest, but will prefer to simply store fiat, despite the fact that inflation will eat up its value with time. Better to have something than to lose everything. Many rich people failed, but they kept moving forward.
