I am also excited for Bitcoin to have a small rally before Christmas. To me it was just a matter of time before the crypto boom would come back. Any price levels above 40k USD are huge and I hope that we are going to stay on those levels for next year and not fall back down again. FOMO can be a risk when we are only running behind the trend and never actually participate. As long as you already own Bitcoins and participate in the current rally, I would try to not start buying large amounts now for the fear of FOMO. In my opinion the best approach to acquire crypto currencies is still the DCA method and it worked really well in 2023. Buying a fixed number of coins every month or every two weeks, is going to lead to a great average purchase price, as the long-term trend of Bitcoins is positive. We need to be realistic when it comes to FOMO, buying now large amounts would mean that we think the rally is just starting and there is a big upside potential. In case you don't own any Bitcoins at all I would consider buying some, in any other case I would just keep my current ones and wait for a new ATH before taking profits.
