Worth noting that, since the currency can also come from a handful of other sources (e.g. trading cosmetics), each cash-out is manually reviewed to ensure that the currency only comes from approved sources (sale of assets, games, products). Because of this, reducing the minimum payout does not scale, and at some point becomes infeasible. The article and video, of course, both fail to mention this.

Maybe throwing more manpower at the problem will let them reduce the minimum rate. Or they could work on altering their infrastructure to support a more automated system, possibly eliminating the minimum rate entirely.
