Are they really hidden gems or only going to be hype coins again?
Well, actually this is my first time to know about this coin, and never hear dit before. But at least, they are listed on CMC.
The most important thing was that these couns have a good team, concept and potential to go *100 minimum.
Did you mean top 100?
Well, after opening the link, I saw their ranks:
https://coinmarketcap.com/currencies/syntropy/ this may have a bigger chance to go to the top 100 if the coin really shows its great increase. However, the volume is still small enough, $619,285.
I don't think COTI will easily go to the top 100, moreover the sis in 327th. And this project was since several years ago. If this is a good coin, this has been in the top 100.
And also about Evedo. Seriously? This is still in more than a thousand rank and this has been from several years ago and still at that rank.
Well, in my opinion, they may be interesting. But, I personally still prefer to put my funds on top coins.
