1 and 1/2 year is not a short period of time and if you check the past history of BTC, there are times where the increase is quick. Don't worry or don't be guilty because $100k is still a modest prediction. Remember, we are at $69k last time and that was only $30k away from $100k which isn't that high. There is no need to spread this FOMO because it's being talked about all the time and many people are now aware of this.
It's still a short time to reach where it will be the expected level, of course looking at the history of how bitcoin went before, but this time it might be a little different and 100K is definitely a passable for the next phase but for me ATH will be over of the.
About Fomo as long as it's not on other coins but for FOMO now it's not a problem.
