HBD is an interesting coin. It's soft-pegged to 1 USD which means that its target price is $1, but it doesn't have to remain exactly 1 USD all the time (depending on various factors).

There are a lot of different economic and technical mechanisms at play, but the general function is that 1 HBD is always redeemable for approximately $1 USD worth of HIVE. Which means that when 1 HBD is trading under $1, it usually* makes sense to buy that 1 HBD and convert it on-chain using the conversion operation into HIVE.. that burns the 1 HBD and gives the user HIVE in exchange.

There are other factors like the haircut rule which can affect the outcome of a conversion -- which means that it's not just a straight shot of "if 1 HBD is less than $1, then I'll make money on a conversion" - so keep that in mind.

As for onboarding, we're bringing in new users from other platforms and primarily educating them with https://leopedia.io/faq and https://leopedia.io/onboard. In the future, we'll integrate a better onboarding process directly on the LeoFinance interface
