I'm gonna just add my 2 cents to your 2 cents , so make it 4 cents, I agree on your opinion on crypto that will stay, but I think the model of the crypto world will change drastically in the future,but I gotta say you shouldn't get angry on such thing, you attacked the man so hard for saying it's scam, everyone is entitled to his own opinion and if anyone think its scam he has low understanding of logic or how the bitcoin cryptocurrency works, I think ICOs are not the right way to raise money for the coins because you put a value to something without value, but if you give away coins away then it makes the coin value goes up from the 0 then yes, Selling a pre-mine of a coin is just like printing out money for the people creating it which should be stopped.
