the fall in Ether prices to below US $ 300 triggers debate among crypto communities. If you think that will go down that far, this will make the crypto world noisy

Same here! I also believe that it will not fall that hard. I think the reason for ETH fall aside from the bearish market is that there are only fewer ICO this year. Most of the ICO last year and new coins are Ethereum based. Despite of he cheaper price, ETH remains in the number two spot in the crypto market.
