#MetaplanetBTCPurchase .Metaplanet's BTC purchase refers to the company's recent acquisition of Bitcoin. However, I couldn't find specific details on the purchase in the search results. Metaplanet seems to be a company involved in business support services, but without more context, it's challenging to provide further information on their Bitcoin purchase.

If you're interested in learning more about Metaplanet's involvement with Bitcoin or their business operations, I suggest checking their official website or financial reports for more information. Would you like more details on Bitcoin or business news ¹?
