Anything is possible and 2021 isn't done yet. We're still more than a month to go before the New Year. However, there are no promises or guarantees that we would see a new all-time high of BTC. We haven't touched $70k yet as of the moment, but from my perspective I can see that there's a good chance. Originally I want to see BTC reaching $100k before the year ends. Nothing is impossible, but don't expect too much for it to happen.
