Yes. There are some restrictions that SMSFs must abide by when investing in cryptocurrencies.
Firstly, as the ATO has stated, SMSFs are prohibited from intentionally acquiring assets from related parties, including your partner, children, business partner or relatives.
Secondly, the assets in your funds must be held separately from your personal assets. Luckily, at Cointree, it's easy to set up a separate account for your SMSF.
Thirdly, all investments must be allowed under the fund's deed and fit their strategy. For any financial guidance for your SMSF, make sure you consult a licensed professional.
