As the price of BTC is increasing on an upward trend and falls only by few bucks, short-term Alternative Coin traders are crying blood. I believe it is due to the upcoming fork. How many more forks are we expecting in the future? It seems that through forks they are pumping the price of btc and once the price becomes stagnant they will start another fork.
You're right it's because of the upcoming fork and that's the reason why there are so many traders that are cutting some of their alt coins and selling it because of the 2 hard forks to come. The price of bitcoin is pumping because everyone is buying bitcoin so that makes the demand of bitcoin higher that is making the price of it reached another all time high.
