In all, the company has added 5,268 BTC to its holdings at an average price of $116,870 per BTC or $615.67 million in total with the purchase.The buy has arrived just nine days after the firm made its record acquisition of 5,419 BTC. This latest purchase has only been slightly smaller than this biggest buy, indicating that the treasury company is currently participating in some rapid accumulation.This is in contrast to the trend developing in the purchases of Strategy (formerly Microstrategy), the popularizer of the Bitcoin corporate treasury strategy.

At the current exchange rate, its value stands at $3.61 billion, implying the company is sitting on an unrealized gain of around 8.4%.A chart shared by CryptoQuant community analyst Maartunn shows how the profit-loss balance of Metaplanet has changed since adopting a Bitcoin treasury strategy.As displayed in the above graph, the recent bearish retrace in Bitcoin has meant that Metaplanet’s holdings have lost some of the gains from during the cryptocurrency’s peak earlier in the year.Another chart posted by the analyst puts into perspective where the company’s break-even line lies.At the moment, Metaplanet’s cost basis sits at $107,912.

According to the company, its “Phase II” will involve a 2027 target of 210,000 BTC, equivalent to 1% of the cryptocurrency’s total circulating supply.BTC PriceBitcoin has seen a jump of almost 4% over the last 24 hours that has taken it back to the $117,600 mark.
