I do not think there is an actual usecase longterm.
Once we can trade RBN/HIVE in-game anyone in this position just buys some RBN with the HIVE that would be locked for collateral and sells RBN when he earns it.
This deal only happened because the marketplace is not ready yet.

Thats a point. But if I can lock a player as safety. You get a player frozen as long as you lend me money. That way I do not need to sale a guy that I might need later.
Can agree with that
