It will grow in value even there is no news. In crypto, holders earn more than traders do in most cases. The price of Polkadot traded below 4$ and now it's above 24$. I do not think there are any traders who didn't book profit or exit from the market around 8$ more than 12$ in the dot. If you are investing in a good project it will grow we just need to avoid our greed and fear.
the problem of traders and investors is their greed. when everyone has control over their passions then harm is avoided. what happens to some of the assets that are pumping right now will indeed get some traders out of trading temporarily for selling their assets in the current bulls. control to determine the correct time to enter and exit will be very important.
I agree with your say because greed will behind them and always tells them not to sell the coin, even if the price increases. Greed will tempt us to hold for more and make more profit, and if we do not have control over ourselves, we will follow our greed, and we will lose a chance to make a profit. We should know how to control greediness so that it will not impact ourselves to take profit.
If you still follow your greed, no matter how high the price can increase, you will not have the opportunity to make a profit. So take your profit while you can buy back the coin at a low price later.
