For a small investment firm, it's a smart move IMO to hedge against the increase in debt of the JPY. It's important to know that continuous inflation would lead to less powerful money and of course, lead to losses. It's a great move by them and I hope it stands completely.
I hope that industries will follow suit because there are still a lot of companies that are not exposed to BTC and if they manage to do it, we all know that the demand for BTC would increase hence an increase in price.
The managers of this relatively small Japanese company are much smarter than government officials in many countries...
Bitcoin performs very poorly as a means of payment due to technological limitations (since it does not allow more than 300,000 transactions per day). However, the first cryptocurrency is an ideal reserve currency. If you use it in this capacity, then all its disadvantages turn into bold advantages.
Bitcoin is a deflationary currency, not an inflationary one (the total number of possible coins is limited to 21,000,000). The Bitcoin blockchain is transparent. This may not be very convenient for individuals, but it is very convenient for banks and large corporations, as it minimizes (almost reduces to zero) the costs of auditing monetary transactions. All this makes the first cryptocurrency an ideal reserve currency. I think that in the near future Bitcoin will be included in the gold and foreign exchange reserves of all Central Banks.
That's why I wrote that Metaplanet's managers are wiser and more prudent than many government officials and owners of large banks and multinational corporations.
