Yup! There's really strong evidence to show that in my region, for example (Southeast Asia), it's been the same old ringleaders perpetrating HYIP scams since the 1990s. That's more than 20 years of the same old guys just doing HYIP and ponzi scams online. Using whichever digital currency was easiest for them to escape detection. Bitcoin in a way is the best so far, because it's irreversible and just easily obtainable by victims.
How theymos and this forum did up the ICO educational post is a wonderful example of what actually works to prevent more scams from happening.
these scammers would use all of the possible things which they can able to scam out people and crypto is the best recipe currently for getting millions of funds.
Busting up would most likely happen when its already late.
