Japanese actresses come to the currency circle to issue coins or NFTs, and the agency copyright fee is not expensive. When the last round of NFTs was popular, the initial quotations were generally between 10,000 and 20,000 US dollars. Later, after several successful raising money, the quotation was fetched to 30,000 to 120,000 US dollars.

They raised their funds after the subsequent market became cold, and they could not even make back the copyright fees. .
