yeah thanks to donators! i reduced payout to 0.001 now.
transaction fee is also 0.001? did you manage to pay less Udjin?
Using sendmany

the fee is 0.136 (!) but for transaction with 131 outputs (130 recipients and my change address)
When I pay by one transaction per address (i.e. using sendtoaddress)
http://explorer.darkcoin.io/tx/007e13fdf7d55c15538334a10dfb39068cff8fd2fa0a07ca793bf8a4a4b2c2a3#o0
the fee is quite often 0.002 for every single transaction (1 recipient and my change address)
Paying to 130 recipients using sendtoaddress would take something between 0.001 *130 = 0.130 and 0.002 * 130 = 0.260
So it's somewhere between "almost the same" and "twice expensive" comparing to sendmany.
I'm staying with sendmany for now...
