I'll give this another 24 hours to resolve and then I'm done with this thread/situation. In the end, I haven't lost anything but time. That's better than losing over $400 on some Amazon scam.
If the OP listens to my advice then you will likely also have lost your freedom

@poksak if the OP gave you a signed message with sufficient bitcoin to pay you and such address still has sufficient bitcoin to pay you then I would give him until morning to pay you when you will contact the police if he has not. Otherwise I would give him 3 days max until you contact the police.
if you contact the police sooner rather then later then NewDeal will have less time to sell/get rid of the S5 that he received so when the police are able to search his house it will be more likely that they find it, meaning a higher chance for a conviction
I don't have an S5. I don't have any bitcoin miners at all. That's the ENTIRE PROBLEM. I HAVE NOTHING BUT A USELESS ITEM THAT I CAN'T EVEN RESELL. I'M BASICALLY HAVING MY REPUTATION RUINED AND I'M NOT EVEN GETTING MONEY OUT OF IT. YOU'RE ESSENTIALLY SUPPORTING MONEY LAUNDERING ON AMAZON.
You are speculating that the OP is engaging in money laundering. You have received no additional hard evidence (besides a message from an unknown sender who you purposefully withheld the identity of). If you did think hat the OP was laundering money as of when you placed the order then you would have been engaged in money laundering as well
