Our current crypto withdrawal minimums are enforced by the specific withdrawal minimums for the network you are withdrawing crypto to (besides DOT and GUSD). For example, even though Gemini does not enforce a specific withdrawal minimum for Bitcoin transactions, you would not able to withdraw less than 0.00000001 BTC (10^-8) because that is the smallest unit of BTC allowed to be sent on the Bitcoin network.
DOT currently has a withdrawal minimum of 1 DOT, while GUSD has a dynamic withdrawal minimum of 10 GUSD ($10).
