People say all sorts of stupid things without thinking its amazing.
Scam has been around for so long even back when we are still using gold as currency or to pay for everything.
You could see some from the old movies that scams has always been around as long as they could use anything that have a value.
Agreed. Even before the creation of Bitcoin, the scammers were fooling people and stealing their money. Bitcoin is an attractive medium for the scammers, because it can be extremely hard to track these criminals once they vanish with someone else's coins. It can be especially hard, if they moves the coins from one country to the other.
Scams have been following humanity and our history is filled with so many colorful and dreadful scams even sometimes perpetrated by famous personalities against unsuspecting ordinary people. Now, with the coming of cryptocurrency, scammers realized that they can magnify their business so well and there are more chances of not being caught. Today, scammers can be so creative on how they can fool people by appealing to their greed and using money or high potential ROI as bait. This is the big reason why ICO is no more attractive and why IEO seems to be taking its place.
They rely on the greed that we all have yet some have more and don't think. People who fall for certain scams are sort of asking for it because what did they expect but then you get more advanced ones and those people I feel bad for.
