In fact, Bitcoin has been in uncharted territory since December 17, when it reached a new all-time high above $23k. It is now in pure price discovery mode. Many enthusiasts claim that this time the rally varies from 2017's craze and may signify a prolonged and a sustained rise for bitcoin.

If we are in a bubble then it is just the start, we haven't reach the top yet. Of course every bubble is going to be burst, but then again, we are now in the levels that we haven't seen before obviously so we really don't know how far will this massive run will go, it could be a 6 year bubble or 3 year bubble so it's hard to predict now as we are just starting and it could end at $100k or even more.

It obviously cannot be a forever bullish market, especially since Bitcoin's bull runs are quite extreme. We're used to those "bubbles", but I always consider them as being a second chance to enter the market at a lower price.

As you said, I've also always known first months of years to be quite crappy for BTC. I expect a little short term consolidation soon, but overall.. I think the bull run has only just begun.
