Cryptocurrency is a revolution in the transaction but also used them to hold a major Scam.
ICO is a round of public fundraising, usually launched by a technical startup. The startup sells cryptocurrency tokens to investors; investors buy in the hope that the company will develop into a large business, which will increase the price of tokens.
There are no exact promises that ICO will turn into a good business. Investors are forced to give credit of trust together with their money. This is where the Scam begins.
Scammers on ICO's now have become sophisticated also in their ways to deceive people. No matter how good we are in our research, these people have ways to scam others. That is why regulations by goverment are being done right now.
