to analyze the right time to buy and sell bitcoin then you can predict the price movements of bitcoin and some other cryptocurrency and I don't think it will be possible for you to predict but if you have very much experience and expertise you might do
If you have the ability to analyze the market on technical grounds then you deserve to give the future price and may it right. If you can judge the investors mind what they want then it will be easy for you to give estimated price. But always say that it is expected and not guaranteed, otherwise people will use slang language about you which is not good.
