This is the ideal, however I can say that there are many good ways to find ICO projects that can be reliable:
1.-Search in Bitcointalk, here the guarantee is greater, since many members are aware of their own investigations and are hardly wrong.
2-Search in CMC the projects that are currently being top, and see them, investigate them and decide if it is good to make an investment or not.
If at least these two are met, it is likely to find an ICO project that can benefit, however the trend is not based on ICOs, the trend is currently taking place in NFT games and everything that has to do with NFTs.
