According to BlockBeats, CryptoQuant founder Ki Young Ju stated that Bitcoin is showing a deflationary trend. The rate at which Strategy purchases BTC exceeds the mining rate, and the 555,000 BTC held are non-liquid assets with no plans for sale.
Just MSTR's holdings alone have resulted in an annual deflation rate of -2.23%, and with other stable institutional holders, the deflation rate could be even higher.
