Man some good advice in this thread. There are so many unrealistic projects out there that look really flashy and cool. I've found that I have to really look at the project not from a "Wow this looks cool" perspective but "is this even possible right now". For example, there are these great "green" projects that plan to bring renewable energy to the blockchain but in some countries it takes forever to get a license to even distribute energy, the cost of wind turbines is extremely expensive and the fact that they took on a worldwide initiative was too ambitious. Since then I've tried to pick more realistic projects even though they aren't as flashy.
