It is indeed a very helpful post for understanding about two different types of token.I have seen the launch of tons of ICO and token this year.But I don't understand why people should buy their tokens.

I mean most of the ICO or Token launch doesn't seem very promising to me.I don't know how long this token business should sustain.Many people invest their money for buying tokens and then they fail to make a profit out of it.Sometimes they also lose their investment instead of gaining anything.
