In what time period are you thinking BTC could hit 100k? I doubt that we will see 6 figures in the near future. I don't think that retail FOMO will make people buy Bitcoin for 100k. They'll probably rather hope to find a cheap altcoin to make them rich than buying a small fraction of BTC. So I think this FOMO would rather be benefitial for altcoins than Bitcoin and surely won't push Bitcoin to 100k. At least that's my guess.
