Well the one thing you need to know before investing in any of them is that 90% of them are going to fail and only a handful of them are going to survive. The coins with great product and real world use cases are the ones which are going to survive. Its just like startup culture where only a few become successful.
Yeah just like what fanchain do ... A coin that coming To solve real problem on sports fans where you'll generates a token every time you creates content to encourage those sports fans supporting in fair way through community conversation that later get rewarded to trade it for merchandise in a cooperated e-commerce .
The point is that an adoption would make coins survive longer due strong supports , yeah clearly that's the reason.
Not only 90% but i do rather give it on 97% which most projects do succeed and able to gain or do have share on entire marketscap. Too many altcoins indeed which it do really comes to a point that most of them are just copying on one others idea with some a little add up then theyre good to go to make such ICO hoping that someone would able to be fooled out to invested on such project. We can advise things very easy but implying those things to ourselves is already hard.
