If you search up the price predictions of cryptocurrencies, you'll find the opinion of every person out there. However, it's a different story when credible, successful people put out their opinion. I have seen the price prediction of bitcoin ranging from $100,000 to $1,000,000, but very few of them are credible. A lot of these predictions are most likely just random numbers thrown out to get attention.
Bitcoin analysts all over the world have begun using precise statistics that are based on bitcoins market history to predict realistic price points. Using on-chain data, these analysts are able to view what is actually happening in the network and can feasibly predict bitcoin reaching $100,000 by the end of 2021.
