I agree that Tether is very likely to be scam and will not likely end well for hedgers/hodlers. However, I suggest putting Tether into LTC, NEO and ETH is more strategic than just putting it all in ETH. ETH I fear may become the BTC of smart contract platforms. It's an amazing team, but currently there are critical issues that still need to be solved with regard to transaction time and scalability.
I suggest NEO because it is a scalable, much faster (with promises quadruple VISA transaction speeds) smart contract platform that is still significantly undervalued. I suggest LTC because I do not under-estimate the likely hood of LTC becoming the first cypto to be used as currency. And when the Lightening Network is implemented, I think it will see astonishing gains, because it will be the basis of so many value transactions. OMG has me optimistic about the future of ETH, but OMG is still a much younger project than LTC and NEO. But definitely over the first half of this year, ETH is still a solid hold I believe. I just believe with regard to long term hodling, NEO and LTC are more promising.
