It is scary to invest in something new for the first time. And those who can overcome this fear are the winners. Bitcoin is no exception in life. Could anyone have imagined that the price of Bitcoin would be so high? Maybe we still can't imagine what the price of Bitcoin will be like in the next five or 10 years. It may be beyond our imagination, just like before. Many people regret that they could have invested $100 at that time. I think people will regret it in the future too, when the price of Bitcoin reaches one billion, they will remember the present.
It's very understandable when someone is scared of investing in pump and dumps or would I say shitty coins rather but then when one have got to know the basics of what Bitcoin investment is all about then the person shouldn't have any reason to fear expect they have no means of generating a discretionary which in return could trigger FOMO, maybe some people who discovered it earlier might have been scared cause they thought it was a scam and didn't have a vision of what it would be in future, well that's understandable too.
However, i see no reason why people should be scared of it currently, especially after seeing how it's improved over the years, their first thought should be, if the coin could get to this point in space of 15 years then I could do better in future, that alone should motivate them into taking that bold step and invest instead of getting scared.
