BitFund stores the majority of our client's cryptocurrencies in Cold Storage. This refers to keeping the reserve of cryptocurrencies offline.
At any point in time 90%+ of our clients' cryptocurrencies are stored in Deep Cold Storage. Much like Cold Storage, this reserve of cryptocurrencies is kept offline as well as being placed off-site in physically secure vaults.
BitFund takes all reasonable precautions to protect against any risk of clients' cryptocurrencies being hacked or stolen.
