You need to read news from several crypto media that review several Blockchain projects that have good potential, such as Cryptodiffer, ICO Analytics, Monoico, ICODrops. I have followed the news of several projects from there.
Yes it is true that with great will we must be diligent in reading news about the development of Crypto in order to always know what is happening, it can be said this year is worse because there are some good projects and too many Scammers. We can determine for ourselves with a strong analysis of course and I'm sure many new projects are pretty good.
