In bear market you should expect Bitcoin decrease 80% in value so from $60k to $12k if bear market starts now. It will of course not happen immediately but will take over a year time. Hopefully we will see Bitcoin price way over $60k so that 80% drop will not be so low.
Bitcoin price won't drop more than $ 40k or around 30% from its current price. I think that the Bitcoin bear market this year is only around minus 30% or 40% of its current price.
Bitcoin still moving strong and with how the corrections being overcome for the past few weeks, still showing bullish, and we are still in the $50K level. Your assumption still positive might experienced some correction to the point that it will hit that low, but after that it possibly bounce back just how it's doing right now.
Bear market or correction is always around, always depending from how investors and traders will support the market.
