guess u dont know how the system works..
if they have proof of communications btween the two parties then that alone is enough for 'conspiracy". then theres proof of FIAT bank transfers.
these days saying "i didnt know" is not enough. thats what government are trying to push, for people to learn everyones life story before moving money to be 100% sure its not used for illegal activity.
so if there was even the smallest indication shrem knew any illicit possible uses of the funds, then pleading innocent wont help. he would have to have lots of documents and proof of no knowledge, which is harder to prove.
so why plead innocent if they have any indication that is provable against him, meaning a lengthier sentance due to basically lying under oath.. or plead guilty and get a light sentance for the things he did actually do and maybe get a deal to have other charges he didnt do thrown out, due to him being honest and above board
