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 $100k before the year ends. Nothing is impossible, but don't expect too much for it to happen.
The hope of 100K for this year is still alive in many people's heart but in reality i think bitcoin is looking too much weak here and i fear that 69,000$ may be the high for this bull run. If you remember Elon Musk also tweeted a picture showing bitcoin price exact at 69,000$.
