You're assuming that the 200bn is all customer money. This is very doubtful to me considering that many times Tether magically starts minting billions of new coins to buy Bitcoin whenever Bitcoin prices start falling
You're also assuming that they make 7bn in profit per year just by keeping this rdiciulously large amount of money in a bank, but their own notation says that only 105bn is held as US treasury bills. The rest of the money is effectively invested, whether in gold or bitcoin or corporate bonds or loans. All subject to going down aswell as up.
Luckily for the cryptocurrency sector, Tether makes it so ridiculously hard to turn Tether into money that their bullshit probably won't be discovered for a long time, so the make believe valuations of bitcoin can stay as they are
