At this time we can sell something because alt coin or token now high price but ETH can going to high more i think because they launch ETH2.0 so investor invest in this coin ETH sell off is good for now and get hope something.
I don't believe ETH will be able to release 2.0 this year. no official announcements from the project team. Who said that Ethereum's growth has some reason?
There has not been any news regarding this matter but surely people will believe it because news 2.0 will appear in the future. This is why the price of ETH has surpassed $300 in recent days. However, if you have made a profit then you may decide to sell out as the market may soon have a major correction in the next few months. I no longer have any ETH and have sold it since yesterday because I think this price is good for my profit.
