I don't think it is panic time yet because i think that it will reach 10k and then slowly go down in value but i don't think that bitcoin will go back to like 100 dollars i think it will stay around 5k and maybe even rise higher if bitcoin will become popular.
If we look at the current market price of bitcoin, then well get to know this thing that bitcoin is at its peak value and that its market price is not falling at all. Even if there comes a time when the, market price of bitcoin falls down, there is no point of getting panic. This will only result in huge amount of loss. So you actually need to cash those moments by buying more number of bitcoins.
