Tethers are fake money that are treated in crypto world as if it is USD. They were created around 2014, and for years lied that every tether they release into circulation is represented by 1 USD in their bank account. Once this fraud was exposed, they new lie is that they are backed by some commercial papers, and reality they only have a 3% of cash to represent 70+ billions they printed.
This is where it gets interesting, with 70 billions they would be within top 10 commercial paper holders in the world, however not a single commercial paper desk (and it is small group where everyone know each other) have ever seen them trading a single commercial paper.
And this fake shit represents 70% of crypto daily volume.
Essentially they behave like "Crypto Fed" and just print fake money to push Cryptos ever higher. most were printed over last year pushing crypto to ridiculous levels. They back to minting a billion every few days again.
Here are just few articles, there are tons of others:

Now ask yourself, why would anyone short such market, where fake money keep pushing market cap ever higher??????????
Where it gets sad for me personally, is that knowing the above, I thought they would be shut down any day, and this would absolutely crash Crypto market, and this is what kept me from inventing into it. Oh well.

They recently had to pay measly 41 million for lies around 2016, imagine how empowered they are now.
