now a days, crypto market also behaving like share market, when a positive news comes to the market, market start rising and when negative news comes, market follow that negative trend. Many rumors are running in the crypto market about btc and people reacting to every rumor with news trend ( negative/positive ). Everything will be cleared after 1st august and again, market start moving in its regular mode.
That's what happens when investors start to invest into crypto to turn profits. They can care less about long term success of coins as long as they make money per trade.
That's normal in the market, the price are volatile so people who have a good amount of capital in trading can take advantage on it but
still holding for long term is still better. I believe those who trade actively are also holding a lot of different coins for the future.
