It's perfect time to buy Ethereum because its price now below 600$ . I think you will never loss if you buy now. What you think about it ?
You are right, once you see that the price of eth is below $600 then it is the time for you to buy the coin before the price starts to recover again. It is always a good idea to buy coins when they get to low prices that no one thought that they would get to so that when people start catching up to buy the coins, you will already have coins when the prices start growing.
