币界网报道：Michael Saylor reignited discussions about Bitcoin sovereignty after Japanese investment firm Metaplanet announced its purchase of 1,111 BTC (worth ~$72M) as part of its treasury strategy. The MicroStrategy executive tweeted that Metaplanet’s move signals a shift toward "Bitcoin as sovereign technology," positioning it as a hedge against economic instability. Metaplanet cited Japan’s debt-to-GDP ratio and yen depreciation as key reasons for adopting Bitcoin, mirroring MicroStrategy’s corporate treasury approach. The firm plans further BTC acquisitions using yen proceeds from bond sales, with shares surging 10% post-announcement. Saylor emphasized Bitcoin’s role in corporate financial independence, while critics question its volatility as a reserve asset. The debate continues as more firms weigh BTC adoption amid global monetary uncertainty.
