Alternative cryptocurrency is facing huge decline from April. There are at least 50 tokens (that I know) are not listed on any exchange from past one year or not distributed from bounty owners. Interesting fact is that all of these bounties have good/best ranking on bounty ranking websites. Do you have or identified any new method to evaluate a bounty project ??
Do not rely on those ICO rating, I've seen ICO with a good project but failed to generate funds, they did not even meet their softcap, instead check the scam sections if they are listed there and if they do not, check the people behind these projects and feedback from the community follow the dev's update and their channel, if they failed to give updates, then it's not safe to invest here.
