Do you think it's a good time to buy or sell?
From a long term investment perspective, regardless of the market situation it is always a good time to buy bitcoin because it has a tremendous amount of potential to grow. Look at the peak of the last major bubble for instance. It was about $19k which means even if you had bought at the peak, you would have still made a lot of profit now that price is $65k-67k.
But of course you always want to make your investment at the best time possible which means inside the dips. That means when price crashed a little while ago below $60k that was the fantastic opportunity to buy bitcoin. Something a lot of people miss out on because they are usually scared or have fallen for the FUD.
Considering how we still aren't in a major bull run, there is no bubble and also because price is below intrinsic value, any price we hit below $70k is still a golden opportunity to enter.
