In order to have a fully featured view for crypto, we will need to:

• Enable support for a variety of crypto prices in Synth API
• Build a tailored view (similar to investments) so that users can track crypto holdings
• Add the ability to link wallets / exchange holdings

Due to our lack of support for this, our current suggestion is to create a "value only" crypto account that tracks the overall value of all crypto owned:

This will allow you to include an approximate crypto value in your overall net worth while waiting for our official Crypto views.

We also have basic support for BTC currency exchange, so you can create a barebones setup as shown below where you track Bitcoin in one crypto account and "everything else" in another:

This is our recommendation for right now, but we do have "Crypto Views" on the roadmap:
