ethereum it's not a revolution, because it is based on what bitcoin is based too and other altcoin also are based on, which is the blockchain, until you change this, you can not call any coin a revolution, i see them as a clone
Indeed. Bitcoin is the real revolution. Everything else is derivative. Sure, Ethereum is cool, but what Ethereum does, can be done under a Bitcoin sidechain, and in fact it will (see Rootstock).
The idea of a TC computer is still a bad idea in my book, that's why I just can't fully trust Ethereum, I think some day some sort of huge bug will be found, you never know with TC. On the other hand, Bitcoin is simpler, and thanks to this, robust as a rock.
