I believe that ICO is an excellent opportunity for the development of many businesses that for various reasons can not get the capital to start. And scammers they are everywhere and they need to fight.
In my opinion the future of digital currency is very bright and people are turning towards digital currency. Digital currency will take over the currency market and all other currencies (paper and fiat) will disappear from the market. People will enjoy cashless world in the future. it will be a different experience for those who have never used digital currency till date.
