Casper protocol will solve all Ethereum scalability problems. That will hopefully come by the end of this year. So, for long time investors it is time to fill the bags.
yeah... it will be the new beginning of Ethereum journey. The core team had already spent 4 years on this.
I would start filling my bags now although I have enough ETH in my wallet, I am really confident that ETH will replace bitcoin one day because it has
real product that bitcoin. The thing that made me convince myself to invest is that there are a lot of ICOs now that are using ETH platform and they are successful so it is not impossible for ETH to pump extremely in time.
