To put it quite honestly - we just haven't got to it yet! Each day we receive multiple requests for new exchanges to be added, so our backlog is always expanding.
We always prioritise based on user demand so please get in touch if there is an exchange you would like to connect to. We are also looking into a public roadmap where you will be able to see what we are working on as well as upvote requests.
We are currently looking into:
BitMEX, Bitrue, Bybit, Celsius, Crypto.com, Deribit, Gemini, Uphold and more...
What to do in the short term
In the meantime, we recommend creating a custom account and adding your data by CSV (or manually). Find out how to do that here. Even though your data won't be synced in real-time, this will provide a more accurate overview of your crypto and tax.
