Investing in cryptocurrency is high risk because too many fraud projects and all you need to remember is trust no one. Dont follow the hype of project if you dont understand anything about the project.
just buy a crypto currency that is already in the top 10 coinmarketcap, or buy in binance,
don't follow an obscure ICO or IEO, of course you could be hit by a scammer
You should change your perspective as any IEO that ran on the major exchange site like OKEX and BINANCE will always bring very good profit for buyers and I think that's not true at all to call both ICO and IEO were scam.
