If you have been into crypto for like 3 months, you will be able to differentiate the different between legit project and shit projects. The rule of thumb of a good coin is the community. How large is the community and How loyalty are them? Because if no one is using it, then it is dead. Most of the 2017 ICO tokens are either dead or struggling to get funds to continue. DeFi is going to beat the crap out of them.
