I find Bitcoin payments (Lightning payments) incredibly convenient because they allow for instant transactions, even from people located far away.

When someone living on the other side of the world purchased an item, I was able to receive Bitcoin instantly, without the heavy fees often associated with traditional payment systems.

I hope the convenience of Bitcoin as a global currency, transcending national borders, will become widely recognized in Japan in the future.
