i was involved with that site too... ended up doing a year in prison in bulgaria about it... but NGU is not a side effect, it's part of what's going on, this is legit money, this is cash, this is a store of value, and with LN it is a full blown MoE as well, and grey markets need real money, bitcoin is real money, so the whole thing caught fire

sadly the monaros camp this part of the business and constantly berate bitcoiners and try to campaign to abolish bitcoin for darkweb trades but they are just the shrapnel from one of the many efforts of spooks to delegitimize and impede the progress of bitcoin

they won't win, and NGU is part of why, as is actual freedom, and money not being robbed by the issuers
