Hypes will always exist while Crypto Market is growing. I do believe Hypes are the reasons why the crypto market is growing because investors are putting and getting their money at the same time.
When the Crypto market goes up then everyone would be happy because their Crypto Assets are growing in values as well, otherwise when the Crypto Market goes down then investors and traders are grabbing the opportunity because almost all Cryptos and coins are very cheap and when the Crypto Market recovers, they could get higher profits.
