CoinJar’s digital currency exchange services are operated in Australia by CoinJar Australia Pty Ltd ACN 648 570 807, a registered digital currency exchange provider with AUSTRAC; and in the United Kingdom by CoinJar UK Limited (company number 8905988), registered by the Financial Conduct Authority as a Cryptoasset Exchange Provider and Custodian Wallet Provider in the United Kingdom under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017, as amended (Firm Reference No. 928767).

Like all investments, cryptoassets carry risk. Due to the potential volatility of the cryptoasset markets, the value of your investments may fall significantly and lead to total loss. Cryptoassets are complex and are unregulated in the UK, and you are unable to access the UK Financial Service Compensation Scheme or the UK Financial Ombudsman Service. We use third party banking, safekeeping and payment providers, and the failure of any of these providers could also lead to a loss of your assets. We recommend you obtain financial advice before making a decision to use your credit card to purchase cryptoassets or to invest in cryptoassets. Capital Gains Tax may be payable on profits.
