I am a little bit disappointed on Ethereum, because some other altcoins are doing better than Ethereum. It becomes one of the most volatile currency nowadays. I agree with you that it is difficult to pick the right time for sale and buy Ethereum. I hope, with the 2.0 upgrade, Ethereum will be back on the previous position when Ethereum followed Bitcoin movements, Bitcoin at 10K USD means Ethereum at 800-1000 USD!
