There are a few things that can hasten the collapse of this ponzi. in no particular order of likelihood:
1) Multiple people keep reporting this to the SEC and City of London, among other regulators.
https://www.sec.gov/https://www.cityoflondon.gov.uk/2) Coinmarketcap & Coincheckup delist them. Although there is debate on whether they should remain neutral, or if they have some obligation to act when a known ponzi scheme gets into the top echelon of the marketcap.
https://coincheckup.com/https://coinmarketcap.com/3) The exposure of this ponzi is spread enough for the new investors to dwindle, eventually limiting payout to current investors and having the whole thing collapse.
I think it's going to take a concentrated effort by multiple people to bring this scam crashing down. I don't see any other way forward.
