If ETH eliminates the shortcomings of its network and launches Casper, it will grow independently of the market. I have bought myself a little ETH for further sale in the future.
Why do people always have a doubt in the future of Ethereum even tho it has proven itself in the last couple of years. Ethereum network is the Most common platform usee by the ICO's for launching their token, thus it is one of the most important Alts in the market or in the economy.
I also think that Casper will affect it's price if buterin will launch it. Good thing you bought at a bargain price. 85 % from it ATH is a great difference in buying.
