I don't think it is for a few reasons. Firstly, they've already shown how brazen they can be when it comes to cheating or just doing whatever the hell they want. If they really wanted to crash the dollar, they would both use funds with more exposure to the big investment banks, and this the federal reserve. They also would do it super quick. This short has been going for a very long time, at least a few months. Why would they feel the need to drag it out for so long. Secondly, if that was the case, the shares would be bought up by other institutions or foreign agents (unless you consider WSB to be part of the glow in the darks). Instead they've pushed this to retail investors, and other bums that have nothing better to do with their time than occupy an underwater basket weaving forum (4chan), or circlejerk (reddit). The people that this is being pushed to are absolute normies. If they were going to crash the dollar, they'd have made sure that their friends were well prepared to weather the storm. The last thing they'd want is a new generation of millionaires (that already cashed out most of their winnings to stable assets anyway) that are hell bent on destroying them.
