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.
Well this is what happens when people want easy and fast money. It is possible but with it comes huge risk involved. Of course where there is money to be made there are scammers that are trying to scam you, they exists everywhere and crypto comes as no exception. Thats why people shouldn't based their opinion on where to invest their money based on some small amount of data but rather should investigate deeper themselves.
