Metaplanet aims for large-scale expansion

Metaplanet has scaled up its Bitcoin buys at a rapid pace. The current announcement follows the company’s Tuesday issuance of a notice informing investors that its board of directors has approved an additional capital contribution of up to $5 billion.

The company did not disclose how much had been raised so far but said the contribution will “significantly accelerate” the implementation of its so-called “555 Million Plan.”

As part of its 555 million plan, Metaplanet intends to buy 201,112 BTC by 2027 at a cost of over $21 billion at current prices. The company previously announced plans to hold 100,000 Bitcoin by 2026.
