Yes. For guided tutorials on Bitfinex, our features and how to navigate between different sections, please see the Tours & Guides section, located in the Bitfinex footer.
Here you will find a comprehensive Bitfinex guide, tips & tricks and specific guides to wallets, exchange trading, margin trading and margin funding.
Unfortunately we do not currently offer a demo account allowing for site-wide navigation or the placing of paper trade orders. This is a feature we are excited about and it is on our to-do list.
To find the Tours & Guides section, look for the Support section in your Bitfinex footer, choose Tours & Guides and then pick the topic you wish to learn about (see below for a visual representation of this).
