Nobody give exact values and predictions about the market because it depends upon the market and user base. Only few time their guessing may correct but not up to the mark. As trader we have to keep learning and learning.
yes i think its nobody can give exact value for market trading, any people just prediction about market movement
based on graphics indication and the market news from bitcoin.com or coindesk.com
so I think we should always update about market developments from time to time and also see the movement of coins. because there is no fundamental thing that can be a benchmark price of a coin during trading
