If the price of bitcoin somehow falls below $8,000...it is an opportunity to buy more. The price slump would have been something to worry about so much if the situation is a case where there is a new digital innovation that is threatening to take the place of bitcoins, one could easily see such a situation then as bitcoin loosing the battle, but currently this is not the case, bitcoin is still a big deal.
You are right, but likely bitcoin can not fall below $10000 ever again, not to talk of $8000. Bitcoin price is still volatile, but not volatile if compared to the past time. Bitcoin all time high in 2017 was around $20000, it falled to around $4000 in 2019 and 2020 before making it up to around $69000 all-time-high in 2021. If the volatility is calculated to be around 5x before the last halving, it is less volatile than the past. The volatility should not be more than or up to that of last halving during this times.
Basically, krypto is a risky asset that is classified as the most volatile compared to other assets such as gold and stocks, the price of bitcoin is also easy to influence the sentiment of its supporters, but even though the price of bitcoin drops like raindrops, I am very sure investors will take the opportunity to buy bitcoin when the price goes down, including myself will buy bitcoin, because I also believe the price of bitcoin will definitely increase someday.
We should not compare the price of other cryptocurrencies to the price of bitcoin, altcoins are more volatile and riskier. Although, bitcoin can be more volatile than gold, but it reached all-time-high and that still also makes it a store of value in long term.
About stock, bitcoin price is less volatile than many stocks.
