Owing to the growth of the crypto space as of 2017 ICOs gained massive attention thus fraudulent individuals saw it as an opportunity to scam investors. Therefore with that growth and as well hype, throughout last year ICOs dealt mercilessly with investors. But now we have learnt the hard way thereby knowing how to protect ourselves.
People didn't still learn on past experiences with ICO because look at on the current IEO,it might have a different system way of acquiring or supporting projects
but it isn't really that different with fraud projects in the years past.They don't deliver something new IEO or ICO,if you aren't aware or careful enough you would still lose money.
