In 2018 bitcoin once touched 8000$, but in my opinion it is impossible to return to the 2018 price.
The lowest by that year was $3k. Well, I don't want to say it but everything on the market is possible, with positive and negative price predictions.
even if it drops by 20,000$ at most. Because since 2016 I know bitcoin has never returned to the price of the previous 4 years.
It's because of the halving that happened by that year. We know that every halving, there's a significant effect and impact on the price of bitcoin and as we approach the next one, a lot of possibilities can happen. But don't be confident so that it won't hurt you as you expect.
