You think many people are as enlighten as they look? Listen to them speak and you'll see reasons why scammers are having an easy payday.
People are very easy to fool and they're ready to give you their money when you can make them believe that you don't need it. Altcoins are doing it everyday, new altcoins are stealing people money and more will still invest so is crypto scams all over the internet.
There are still many who fall for these kinds of scams, it really comes down to a lack of knowledge. As they say, it's just easy money or HYIP. Even though regulations are getting tighter, some still manage to slip through, and most of these scams happen in poor countries.
Ignorance that's the excuse they'll be giving but why will someone join an industry and not do his findings to stay updated. The golden rule is, "if it's looking too good to be true, it usually is".
Why will you fall for someone promising you unrealistic profits, sometimes I just feel people getting scam deserve it because they're making the job of the scammers so easy.
Scams comes in different approaches but they all have similar things which are unrealistic/high rewards. Stay away from those and you'll be safe from scams
