The films do not discuss matters and complexities in detail, they know that it is difficult to track bitcoin so they add them to the movie or series in order to gain more sense for their story and make it more believable.
I expect that after many people know that it is possible to track bitcoin transactions, they will appear using Monero or any privacy coins for purchase of these equipment and devices.
if you have power to earn 200000 in bitcoin will have more ways to hide it.
