Are you not familiar with how things work in the US? The burden is to prove one overt act in a conspiracy charge, you can list all the bullshit you want and there is no need to prove it all beyond reasonable doubt.
Why were all the actual murder for hire charges dropped and instead included in a side notes of a conspiracy sentencing? Seems obvious to me that it was because there is no way they would get a conviction.
There was an irc chat log and nothing more offered as evidence. Later the agent involved was convicted of stealing BTC from defendant. You could say the relevant fact is that an irc log on a compromised computer had a questionable chain of evidence. The logical error of assuming something quoted in a sentencing as fact is "appeal to authority" if you want to look it up.
