About us

As our motto reveals, our service is a Safe and Secure Cryptocurrency exchange

BTCBOX is officially registered at Japan’s Financial Services Agency, and we currently are the longest continued cryptocurrency exchange for order book trading of Bitcoin in Japan. Since our service started in April 2014, we have not had one leakage or accident in 5 years, and our sales points are due to high security level. The coins currently  accepted for trade at our company are Bitcoin (BTC), Bitcoin Cash (BCH), Ethereum (ETH) and LiteCoin (LTC).

As our customer support system, we offer support by phone, email and chatting portal, and provide customer service in Japanese, English and Chinese. All the internal departments do not depend on each other and work independently having a good grip of all the internal information, so that we can provide a high quality customer support.

The customer assets are stored in a evaluated and verified safe wallet. That is programmed to be virtually offline, thus it is preventing cyber attacks and internet threats. Furthermore, the wallet itself is fully protected against theft and losses.

It is not only our wallets, but the main order book trade system and our trading venue have cleared verification tests more than 1000 times so that it maintains the system making it highly reliable. On top of that, we have a second verification step in order to maintain our highly security level.
