I don't think that there is anyone who can answer that question - It's a relatively difficult one and we are all going to debate, assume all day but what I have noticed is that scammers are surrounding us- scammers are people who are lazy and they just want to benefit from the work of others. Scammers just look to earn money they slightly worked for - they just want to take people's hardly earned money without thinking of the consequences. I have been scammed several times and I am writing this from my personal experience - and the fact is - no one knows who is responsible for all the scam projects. If you want someone to blame...probably the perfect candidate will be Satoshi Nakamoto for inventing the blockchain.
