From my experience evaluating brokers, it’s important to check not just their licensing, but also their specific offerings and limitations. With SANKO, my observations are that despite being regulated in Japan and holding a retail forex license, its core focus appears to be on traditional financial instruments such as stocks, futures, options, bonds, ETFs, and REITs. I did not find any evidence that SANKO deals in cryptocurrencies or even offers crypto trading. Additionally, there’s a lack of clear information about funding methods; their website is only available in Japanese and the available context does not mention support for crypto deposits such as Bitcoin or USDT. Given my own cautious approach when handling account funding, I would not assume support for crypto transfers without explicit confirmation. Japanese-regulated brokers, particularly those primarily serving the domestic market, tend to adopt traditional funding channels rather than newer digital assets. For me, this means I’d avoid attempting to fund a SANKO account with cryptocurrencies until official, up-to-date guidance is provided directly by the broker. In my experience, when working with a broker that isn’t clear or transparent about deposit options, I always recommend erring on the side of caution and using only the methods explicitly listed and confirmed by their customer service.
