Does this way of raising money to have a future for the startups?
Hmm, still scratching my head how a newbie got his first post predicting all about the negative sides of an investment into ICO. So you just got here and think that ICO are scams ?
It's not completely true. There are hundreds of ICO which are fully successful with whatever they started and they have followed the roadmap until the end of ICO project. They have given big profits and return of investment to their shareholders and I have been through it many times.
So just knock off and try to learn about ICO in professional manner.
If bitcoin is oxygen then ICO are water, both of them are essential and isolated.
