The minimum payout is shown on the main page of every coin's pool.
For Ethereum the minimum payout is 0.05 ETH, for other Dagger Hashimoto coins it is 0.1 and 0.01 for Equihash coins.
It is not possible to change the payment threshold at the moment. However, don't worry we pay the tx fees ourselves for all the coins except Monero and Grin.
