I believe Ethereum price will still go up and therefor still not to late to buy ETH.
This is a good advice, buy on top! If you don't know when to buy, just wait for the price rise and new peak for buying, it's always awesome moment for buying!
If you didn't notice I was sarcastic, good buying was two weeks ago, now we are close to selling point. I sold some already, I wait to see will it rise a bit more to sell again, and after that comes dump, like always! And it's not just Ethereum, I have some sell orders for other coins, my bitcoin sell orders passed this morning after bitcoin hit 10.9k. I expect dump in next few days and going back under 10k. Question is will it rise a bit more, or this is the top.
