Fear of missing out is one of the factors that brings failure to investment however most people has actually fall a victim of Bitcoin market structure, were as they believe that since the Bitcoin price is a bit lower, they try every means possible even to the extend of getting a loan in other to accumulate a  huge number of bitcoin because of the fear that they may not get the right chance again to see Bitcoin on that particular price and that perhaps the bitcoin price could moves very higher than there expected entry points.

So actually you are very correct this was a similar issue my colleague had, he saw Bitcoin when the price was still at $25k so considering how far the price had gone before when it made the all Time high so he sees it an advantage to accumulate good number of Bitcoin while he can now so he tried every means possible by using all his savings to acquire the Bitcoin in other not to miss out this opportunity, so it was a good move but the strategy was very aggressive because he had use all his savings in accumulating the Bitcoin and was not upto a month he started feeling the heat due to some pressing needs so he start panicking and the investment became affected and was left with no uption but to sell it off.

Although he was very lucky that before those pressing needs came out, the Bitcoin price had already gone beyond his buying point so instead of losing he made a bit profits, so with that experience he had, he was able to encourage people of the consequences involves on making a rash decision due to the fear of being left out from investment, so no matter how Bitcoin price may drop down is very unwise using all you have to accumulate Bitcoin because later on it may seriously affect your investment, and perhaps in times of Bitcoin no time is late, we can always invest whenever we feel we are ready, but the only different is that it will take a longer time to gather or accumulate your expected amount due to the price increment.
