I hope this month payouts will be made also in 1 piece, as it will faster payout speed, lower transaction costs, also make lower load to etherium network.
If there is 1 transaction per address then it more posible to litlebit spread this transactions in time, to lower load and not make GAS price more expencive.
I made some small reserches and this year time 9-14 dates gas price is more expencive.
also 1-4 dates.
Today for example prices are lowest this month.
