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 ?
There is no doubt that it is a good time to bu Ethereum. Because it is a good coin to hold for long term, you are assure that your investment will not go into waste. Grab this one time opportunity while it is available.
There's no good time to buy or whatsoever, the price could go down even deeper or rising and gives you profit but talking about "the right time" kinda wrong, if it can be known, then everyone will be rich.
If you buy right now, you may get a cheap Ethereum but who knows what future holds? it's a merely speculation overall.
