It depends on what strategy you will use and your target.
Bitcoin reaches $68k this year and now it dumps to $55k, I guess it has already dipped hard enough giving us an opportunity to earn in short term. However, it does not guarantee anything as $55k might is already the lowest as it could dip further and that could result to panic transforming the market from bull market to bear market.
yes the bear market has come and is currently dominated by the bear market. But the bitcoin price was able to hold on and eventually bounced back. Chance to buy cheaper before hitting new ATH again.
When the bull market has returned again people will panic buy.
We'll see if before the end of the year bitcoin is able to get a new ATH again.
