If you are referring to two different types of asset accounts, you simply add accounts with those names. See this Guide: Manager Cloud. If you want information about including those accounts in different groups, such as current assets or long-term assets, see this Guide: Manager Cloud.
(I am making no comment about whether this is an appropriate way to account for cryptocurrency investments.)
Regarding “I am making no comment about whether this is an appropriate way to account for cryptocurrency investments.” I believe you are perhaps referring to the way they calculate crypto assets in the USA. From where I live, they have told me that what matters is what I put in and what I withdraw to my bank account and calculate the gains/losses on this.
Daily trades will be seen as sales(and go on my income tax) and long terms crypto holding will be seen as long-term investments.
