hi pos coiner
i want to know if it is possible to mine pos without used gaz ? because i think this isn't profitable if i mine pos by ether transaction..you know wht it is

i can mine 15 POS rewards but if i do an ether transaction for extract them i will be loser..15X0;25POS=~3,5$ it's really small i will do an eth transaction by smart contract an used 200 000 GAZ may 2$.
