The main point of yesterday's article is that a rapid decline is necessary, because only a rapid rate cut can lower the "marginal interest rate" of credit.
A 50 basis point cut in November is not a big deal and creates some soft expectations. I'm not too worried about a soft landing. Other than that, the above situation seems like the best-case scenario for BTC.
The risk of the economy weakening a bit means that US financial policies could change quickly. Also, if the US makes large rate cuts, China will strengthen its fiscal policies.
They used to keep interest rates low because they didn't want the exchange rate to fall too much; but now that the US has changed that, China won't need to do that either.
