No mate, literally no one could predict the Bitcoin's price and we see all such speculation only when the market is upward and we don't see them often during market dip. Bitcoin may even cross $84k or even $100k or even drop below $60 k once again hence we cannot predict much about Bitcoin unless there is a strong factor threatening it's usage which usually results in temporary dump.
If we are all optimistic here, I guess $84k is lesser than what we expect to see in the market. It could be $100k or above, that’s what we want to witness happening in the market. However, bitcoin price is highly volatile that makes it so unpredictable to anticipate a price. Reality is we can witness higher or lower than $84k, and we have no control of that. But if positive news and updates will consistently hit the market, then it’s highly possible for bitcoin price to achieve $100k at the year end or even higher than that.
its the all time high price reached by bitcoin in every bullrun that matters from my honest opinion, we can disregard the volatilty at the mean time because it only mattes when people are trading or investing with short term time it's not gonna be that meaningful for us that aimed higher price with holding long term these volatility at best just a decoration.
so i'm not really worried about whether or not the price of bitcoin gonna reach that high from the data of past all time high and how much percent it climbed up every time.
like you said, bitcoin could reach more than that, most people still don't believe it, but bitcoin can always make surpise price surge.
for good holders that have been holding since many ages ago, they even have set a higher target with the price around millions until they finally cashed out their investment.
