Opinion.

I would say that ICO is the BEST thing that has ever happened to cryptocurrency by this day :)

Seriously. What other single thing is cryptocurrency good for? Money transfer? Nah. Orders of magnitude slower than Visa and the likes. Used mostly (?) to pay for illegal stuff.

Trading? Crazy. Ten percent up or down in an hour (!!), a virtual landmine for 99% of rookie traders. Then what’s left? Mining is senseless, a waste of electricity.

Really, ICO is the only USEFUL application of crypto by far.
