At this point I am the most bullish on Ethereum over any other project. As a programmer I view smart-contracts as one of the most important developments in this space.

Ethereum has more developers (when you include ERC-20 tokens) than any other platform. For me, the whole concept of "Ethereum Killer" projects is laughable. There is no direct competition here. If you want to make gains in one area (speed/efficiency) you have to make sacrifices in another (decentralization/trust). Most smart-contract platforms will find their niche without having to "kill the competition". In fact, many of the killer dapps of the future will be cross platform, existing on multiple chains.

Another huge advantage to having so many coins is diversity and decentralization. EOS might be more centralized than ETH, but EOS and ETH together are more decentralized than if one of them had never existed. Each project gives fresh incentive for new investors/developers to jump on board at the ground floor. We are so used to the big fish eating the small fish that we never stop to consider the metaphor of a school of fish; all protecting each other. That's what open source economy is all about: collaboration and interoperability.

Venture capitalists wrongfully project cutthroat capitalism onto the space, demanding that 90% of all startups die. It isn't going to happen. No single project can corner the market using the traditional tactics of regulation and patents / IP law.
