Tether buying btc to back up USDT with valued asset.
It can only means that USDT might decouple of the USD.
The main purpose of centralized shitcoins like tether is still to be used by day traders and the biggest chunk of the volume still goes into altcoin market. There is not enough bitcoin to be bought to back tether.
Could be Bretton woods moment here.
The next year we could see USDT value against USD will grow.
Unlikely because dollar got its value from United States exerting its power over the rest of the world and forcing others to use it. Tether does not have the same power, not just that we consider it to be a centralized shitcoin so its value can not rise.
Not to mention that the only reason why anybody were using this shitcoin was its stability, if it stops being stable (1:1 with dollar) it stops serving its main purpose as I said at the start meaning it would dump hard.
It may have taken 30-40 years for dedollarisation to speed up but it won't take nearly as long for detetherisation to begin
