Not much profit as customers would only buy once. And even 1 million $ is nothing compared to the risk you'd take in selling this shit. Imagine what they'd do to the guy if they caught him, he'd be convicted for killings hundreds of people and spend the rest of his life in prison. If it was worth it a Cartel would have taken over a long time ago.
I think you are underestimating how much interresting is 1M$ for a criminal. An successfull skilled criminal isn't just El Chapo or Eskobar, those are the top 0,1% of successfull criminals.
I was just watching the documentarie serie "Drugs Lords" in Netflix, and there is an episode about a whole Australian family invested in the heroin business in Melbourne, and their business made 5M a year, the whole of them. Yet they were taking waaaay more risks than someone selling over the internet, if you just sell over the internet, and you take some meticulous precautions (change places and Bitcoin wallets from time to ime, always use TOR, never reveal your identity online etc), you are taking 10 times less risk than a real life operation where you have to meet some contacts, show yourself and engage in more risks.
There are 2 sellers A and B.
They charge that amount as it's dangerous for them to send a drug so you can kill uourself, they are looking at a murder charge.
If you want to do it cheap use SN!!
Only A is proved legit.
And i don't want to get it cheap, i want TO GET IT. is that too much to ask ? Last time i ordered from A it was intercepted by the customs. Having more sellers also gives you more patterns of hiding/labels = more chances TO GET IT.
