Only stupid and moron people will fall for this kind of offer especially in internet online. There is no such thing as easy as that, if its true then there will be no poor people. Its better to stay away with that kind of offer and invest in a legit one with small but true profit.
You are right, investing in altcoin is better than getting stuck in the scam.
I've found such a fraud since 2014 and I'm surprised many people have been deceived until now.
