until now there is no way to predict the price of bitcoin or altcoin in the future, I think you have to analyze it yourself and you dare to accept the risk that will occur.
if there is a way to be able to calculate how the future will come then I think it will actually damage cryptocurrency.
Whales are the most influential on the price and rise or fall of coins and tokens.
All you need to hold is this is the future to come and that will make you a millionaire.
