With a long period of loss, people are desperate to have a profit. And it seems like people are selling of their alts to ride on the bitcoin bull. But with less amount of new investment coming, we would not be able to achieve a huge growth.
Yes, I also agree with your suggestion because I also believe people are selling their altcoin and buying more bitcoin and this affects the price of altcoin because the supply is now higher than the demand but with patience, I believe altcoin will also rise before the end of the year when the market recover from the bear.
