I often hear this theory that tether is just printing bills that are not backed by actual USD... Which I doubt is occurring... But even if it is and every single tether is counterfeit, the market cap of Tether is a mere $1.2 billion. To put that in perspective, Bitcoin's cap is $240 billion. Tether is not a major factor in Bitcoin's price. Sorry.
I put my money on waiting until after Tether [1] fraud gets exposed.
