If the scheme described by the article really exists, then it represents a substantial fraction of the demand for BTC. It's true that such a scheme collapsing would drive demand for BTC from USDT holders up. That's of course assuming they could still trade their USDT. Tether (the company) cancelled $30 million worth of coins stolen from them a few years back which suggests if the company was seized the ability to trade USDT could be disabled. But it's also true that such a scheme collapsing would instantly drive demand for BTC from Tether (the company) to zero. If that demand really is almost 70% of all the demand for BTC then BTC's price should decline significantly.
