I think bitcoin has reached the price of 6 digits in two years, but that irrational is too high. at the moment the price of bitcoin is only $ 8k I think it will take longer to reach $ 100,000. and most people who hold bitcoin will definitely sell their bitcoin when bitcoin has reached a high price of $ 25k. and of course if many sell then this will make the price of bitcoin go down again. so I don't think bitcoin will reach $ 100k in 2021.
