WOAH, WOAH, WOAH.
Wait a second. Tezos has some serious issues you might want to consider:
No Hardforks is just a sham - you can't do it.
Not formally verified.
Potential intellectual property issues.
This does not mean that Tezos will not be a good investment. Speculators can remain irrational much longer than people shorting can remain solvent.
See my old post We don't need to Hardfork: a questionable story about Tezos. - ICO July 1st for more information and support for my claims.
Both Qtum and Tezos will introduce a new governance system designed to prevent chain split like what happened after the DAO disaster, having such measures in place is a lesson learned by these next generation smart contract platforms. I am sure Dan mentioned how EOS will deal with issues like the DAO, although I am not sure yet what measures will be taken on the EOS chain. Regardless, all these new Chains will have a chance to dethrone Ether, something easy to do with the continuous recurring disasters on ETH. I know by now you must have reached a point in time where you do know these issues will not disappear. I am not saying the other chain's won't have issues, most likely they will, but I have serious doubts they will be as incompetent as the people behind Ethereum. Ether to take over Bitcoin's marketcap illusion is gone.
"Dethrone ETH",
Well Ethereum can simply use their governance model if it works. No need to move to a new, less verified project. Besides Tezos is not even formally verified.
"Continuous recurring disasters on ETH."
What disasters do you mention?
Okay so the people behind Ethereum are incompetent. Got it.
