I am also more bullish on Ethereum than on Bitcoin. If you take the speculative aspect out, with all the ICOs done on Ethereum, it generated a real demand for Ether, since you will always need it to run a dezentralized app on it, plus if you want to send your ERC20 tokens, you need it too. And maybe 90% of all tokens issued in ICOs will fail, but those 10% or maybe 1% who are gonna disrupt an industry, will also increase the value of Ethereum in the long run. And a first mover advantage is always big, plus the todays disadvantages in Transaction speed or other shortcomings, will be improved by the development team.
Only mid-term concern I have is, if Vitalik would decide to move on and do something differently. Although there are a lot of great developers on Ethereum, this would hurt Ethereum price a lot... but I will be ready to buy that dip then.
Looking forward to that Raiblock video wanted to get into it, but then price ran away and I didnt wanted to chase the highs (although I was at that time still very early...)
