This is just spurious correlation. As the crypto market has boomed, more activity has been going on everywhere, including increased use of USDT (Tether).
You’re taking a single grant (N=1) that correlated with a massive price increase and then using other time periods (obviously not massive price increases, since most of the time price isnt just massively increasing) to trick people into thinking it is statistically significant.
This is a classic case of abuse of statistics to push a narrative.
Real statisticians have processes and standards for how they analyse the significance of events, with well developed models that take into account MANY variables in their work.
