Provide ability to earn a small APY (similar to online savings accounts like SoFi, Marcus, etc...) on Account Balance and/or Portfolio Value. Doing so for Account Balance could incentivize users to keep their cash balance in Alt rather than continually transfer to a separate bank account to earn interest. This could result in more purchases on Alt Exchange / Liquid Auctions over time. Doing so for Portfolio Value would be similar to crypto holders "staking" to earn interest and thus passive income on the assets.
