Well this would be actually a good contribution to all of us, but there's a problem with this cause it actually rent card 1x at the moment not 3x at the moment. with that problem we may encounter decreasing our RC's until we cant no longer rent a card, I suggest to add a line that could maybe increase also our RC's like transfering dec to someones account so that it could automate, you can check my modified version of this code guys. also thanks to Hive account@wohefengyiyang
