Yield as Margin is an interesting concept, especially for active traders. Think of a trader who has $10,000 set aside. Some of that capital could be earning yield, while another portion is needed to support open positions. @grvt_io wants to let users put eligible Earn balances toward trading margin without giving up the yield those balances generate. If it works as intended, that gives traders another way to manage their capital instead of treating earning and trading as completely separate activities. I'd want to know how the margin requirements work and what happens to those balances when a position moves against you. Those details matter more than the feature's name.
