If you are a developer and you develop a new project and build a good team and after several months of promoting the project you don't met your expectations yet you never give up won't others say bad thing about the project and the teams? This is happening with few good projects in crypto space but many failed to understand, they want their half cake quickly e.g bounty hunters, to say the truth it's not easy to be a developer, not all projects that failed are bad, they might not just meet their expectations
Actually what you said is true, but when someone or rather a team or developers cares deeply about their project or about what they aims to achieve all the bad words people throw at them will only encourage them to do more so as to prove them wrong. Giving up means they were right about the bad words they said, thus only the developers will be at the receiving end. Also, in the outside world many projects passed through that stage and today they are on lips of everyone. Therefore in my own opinion, stick to what you believe in as a developer, do your best, seek advice and help and lastly prove them wrong, it will make you a winner.
