hmm, but is your thrust reallygone, though? I mean - why didn't you trade all of your ETH for BTC, then?
That said - you make some great points in your linked article. I recently put my foot in my mouth when I was speaking to how ETH is like 'BTC 2.0' - but little did I know that it's not entirely decentralized like BTC is, until someone else pointed that out to me. Whoops.... that's definitely a concern for me. That said, its smart contract capabilities are a nice step ahead in terms of BTC.
Looking in the future is never 100% sure, so I never sell a full stack of an asset. Beside this, when my suspicion is right and the banks are hyping it up, the price could rise again and I can dump another half (of my remaining half) later, and so on and on.
Also when RSK won't deliver their promise or just not get adopted, ETH might have a good future over the longer term and then it is good to own some even if it is controlled by the banks. By owning I will have the power to decide when to dump it, so I don't see it as supporting them.
