I don't agree Etherum got it right unless you'r talking about p&d or devs getting rich. We are all working on software that is supposed to handle peoples money. That means we have to get it right first, and then market it. The damage that Eth has done to itself will be very hard to fix. Whales keeping Eth price at artificial high level after disaster only has effect amongst traders hoping to get rich. It has no relevance for adoption amongst ordinary people and businesses, and I can't see why they would use a coin with a dev team that is so reckless.
That said, I totally agree marketing is just as (or more) important as developing. We even have a marketing tool built into our client, the pay to mail feature.
True I actually agree with everything you say here. It was extremely irresponsible to investors what they did with DAO and did with pumping.
We are doing it the right way, less volume now, we market a completed product that we test and can be proud of.
However from a greed perspective ETH did everything to try and be a media darling and shake investors for money. Market first code later.
It's a matter of principal. And we still have tons of room to market and grow.
