Have you ever supported, bought or mined a coin that died later on? Why did you support it? What did you learn from it?
I did few times and the feeling is not good.
Why did I support it? For the usual reason - I saw a potential in the project.
What did I learn from it? Actually nothing, because here we are talking for 4 ICO's in 2017 from 50+ and my ICO criteria remains the same. Just some projects are failing hard.
