Recently, I saw a few Bitcoin and altcoin Price Prediction website like https://walletinvestor.com/forecast/ethereum-prediction and https://longforecast.com/ethereum-price-prediction-2018-2019-2020-2021-eth-to-usd

I'm working on a site and want to add this type of feature in it. Can you guys please suggest how are these sites doing it or how can I build a better tool?

They are guessing. When they guess correctly, they pretend like their guessing algorithm is reliable. When they guess wrong, they hope you'll forget.

It doesn't matter what algorithm they use. In the end, there is no way to know with any certainty what the price is going to do. It's just guessing based on something that they saw in the past.

I'm afraid Mr DannyHamilton was right because the information and technical used to prediction the future price of coins base on past historic data coins.
