We can two zone support 1 and 2 .
Note : If you want to trade and buy dip
1. Buy a fews eth near zone support 1. ETH can go up after hit zone support 1. But you need set stop loss 680 . IF ETH crash down 680, ETH will go down to zone support 2
2. Keep a fews BTC or USDT, Buy around zone support 2 , if ETH crash zone support 1.
In this time, I think should trade top altcoin will good choice
