Predicting the value of the bitcoin or altcoin is genuinely so hard and absolutely, no one can foresee the price of the coin. You cannot predict the exact market worth of any coin, but you can make a guess. Some the expert analyze the chart time to time. They use the chart indicator to gather all the information thought it.
