according to my source she never knew the offer was scam because the offer was fair enough
That's her first mistake. Judge a scam with 'this deal was too good so it is a scam, right?' Don't do it cause the scammers playing around the victim and know exactly what kind of bait they need to lure in, either by pure greed or a well-laid trap hiding behind 'a normal-looking' stuff.
That word explains to us that even if the offer seems fair enough, it doesn't guarantee if the project will not scam because we don't know the truth. We only need to use something that we can afford, so if the project is a scam, we don't lose too much. I am afraid that right now, the scammers will search for the other way to trick people, especially new people because the new people will be an excellent target to get their money. But the old way will still be used by them as many new people don't know that trick, so be careful.
