I heard from my local news that police arrested a person who were scamming people in the name of bitcoin. He was promising double return within 25 days to the investors. Now those who are aware of bitcoin, they would know it is impossible to get a confirmed return from bitcoin and they understand the risk. But still people have fallen for it.
Scammers will always find new ways to scam people. Education and awareness can save from a disaster!
Like kids rushing for a free candy, -Newbies- that don't want to invest or haven't the capital/finance they will rush for ponzi-scheme or free way just to earn Bitcoin or crypto-coin. This mis-conception must be corrected.
