i don't see how much they helped at all because according to the story i've read they caught them by investigating centralized databases which had nothing to do with bitcoin in first place. it was mainly the forum they all hung out and communicated in called "OGUsers", there was also Discord they used and among their accounts in this site they were also used the same Email address and same wallet to connect to Coinbase website and Binance. not to mention that their IP addresses were all the same (no TOR, no VPN,...) and were used in all these places!

this makes me wonder why the hell are the media using the term "mastermind" for these dudes
