I honestly think that ether has potential. And it will have even more potential when it switches to POS. That's why I'm hodling my ether now. 200 ETH 4 DAYZ...
The switch to PoS will remove any uniqueness it has above all other ETH clones. While ETH 1.706's TH/s is pathetic compared to BTC , it is far better than other ETH clones. When Eth becomes PoS, you can bootstrap a wider userbase with free ETH and have it more secure eliminating the need for ETH altogether.
