I also believe the worst it is over. Bitcoin cant lose much of value anymore.

After previous Bitcoin bubbles the BTC price always retraced roughly
90 % from the all-time high. If we assume that the price will develop
in the same way this time, we will see BTC go down to ~1950 $ / BTC.
After April 2013, we only dropped 81% from the high.

We also used to talk about 2012 as a bubble back in the old days. We dropped 50% from the highs when it crashed.
Anyway, it really depends if this is a shorter term consolidation like mid 2012 or mid 2013, or a longer term bear market like 2014. The reality is that none of the bubbles will ever look quite the same as one another. We should be prepared for something different.
I suspect
a bear market of at least 1-2 more years until the next BTC block reward halving.
A multi-year bear market is definitely possible.
