I don't believe in eth as an alt. As for a distributed app platform the technology is interesting, but as for an alt, no.
What's an "alt"?
Alternative to Bitcoin?
Ethereum is a replacement for Bitcoin. It learned from Bitcoin's mistakes and re-architected something better.
In terms of value store, Ethereum matches Bitcoin for security/ease-of-use/etc.
In terms of value transfer, Ethereum is: faster, cheaper, more reliable, more energy efficient.
In terms of value programability, Ethereum is years ahead.
Bitcoin is a 2D blockchain technology that's getting old, is slow and expensive. Ethereum is a lightweight 3D (value store, value transfer and value programability) blockchain for the future.
I repeat myself. I do not consider Eth as a coin at all. It is an interesting technology with the smart contract concept. As a coin it totally lost its credibility after the fork.
