Seems like the exact same MO, just with a blockchain to back it.
Probably or not, there are tons of this kind of scams
A scam will always be a scam. As I have stated yesterday, you just wont learn do you? . Unless everything fall apart in one piece then you will never realize that this kind of thing is a scam to begin with
Most people will never learn
You could have leave with all those profit you made from this scam but you choose not to, Well done
