Sia having a good day. It's always been good to me.
Ethereum is a solution waiting for a problem. People invest in it because they feel like they missed the bitcoin boat and want to get on the next one; which is true for all coins, really, but Ether is just really good at sounding like some world changing super tech. Sia and LBRY on the other hand are used right now for their intended purpose. ETH is used for a cat game and as a means for ICO scams to not need to have their own blockchains and ETH's blocks are already full again after enlarging their block size. By the time ETH finds a real problem, that problem might find another smart contract solution more attractive, like Rootstock.
Ultimately you want to buy an asset that will be bought by people other than speculators. Who is buying ETH to USE it for something and not speculating? ETH's price is entirely unjustified IMO. To make it more worrying to me, I've seen dev quotes suggesting that it should be an inflationary asset because, naturally, it's used as 'fuel' for contracts and wasn't intended to be a payment coin. And on top of it all, it's centrally controlled by a 23 year old with the power to destroy its value any time he pleases which he already demonstrated with the DAO funds.
