So, 81.8K is the highest so far on coinmarketcap. Yesterday, when BTC reached the 80K level and quickly fell down to 79K again. I thought BTC would struggle to reach 81K because there would be some selling pressure at the 80K price range. 80K is a nice round figure to sell if someone is in profit already. So I expected a lot of sales pressure. But the Bulls decided something else and broke that range a couple of times.
The current price is 80.9K, but the market is positive and it can make another new ATH today by crossing the 82K price range. We will see the result tomorrow because today is the first day of the stock market and it affects the online market a little late. I hope ETF investors are still buying and holding.
In a bull market, new ATXs will be normal and very common, so you can get used to it for a while. But I don't think there will be many people willing to sell now, despite reaching round numbers like 80k or 90k, because the market is now in a phase of great positivity and everyone expects growth to continue, it all started with Trump's victory and is still ongoing. As for the round number, at which we will most likely see big sales, it could be 100k, but it will also depend on how quickly we reach these values, if bitcoin reaches 100k before the new year, then I don't think there will be big sales either, because it will be before Trump's inauguration.
and it might carry on creating new ATHs like it did in 2021. This time it is possible that after breaching 90K it might hit 100K. When Bitcoin goes up it keeps on going for few weeks. 
It's natural that after a rally, there would be a drop in price. 
The price is around 89.9k. In just a split second, it increased from 89.4k to 89.9k. If this continues to keep going like that, it'll surpass 100k in no time! We still have some times left until the end of 2024. I hope, I really really hope that it crosses 100k! Fingers crossed!
