Probably never zero again, and most likely never under 20k again.
But it is still possible tonsee it drops like 80% from the last ath, which would be near 20k... which would scare a lot of people... even me lol
Something I could observe about the price of Bitcoin, and that whenever it passes the ATH, it hardly ever falls below the ATH again. For example, when I entered the cryptocurrency market, the price of Bitcoin was less than $900, then it reached $3,100 and when it broke, it went to reach $10,000, but there was a correction and it fell a lot, but it didn't fall below $3,100.
When it recovered, it reached $20,000, but it fell again a lot, but it didn't fall below $10,000. After it recovered, it rose to $69,000 and when it fell, it stayed below $20,000, but it didn't fall below $15,000. Looking at this price history, I believe that the price will not fall below $50,000 anymore. It will probably stop above $69,000 for some time before breaking the ATH. $109,000
