I used to use Splex to rent out my cards and that worked fantastic until it didn't anymore. I guess this started with that 1 DEC per transaction thing and also the lowering of the rewards which kind of killed the incentive to rent cards. (bummer indeed!)
I now just have my SPS staked, my 1 plot of land for grain and my license node that gives me SPS but that is also nearly nothing...Nehhh it aint earning big at the moment
wow a license node is huge investment. I think that will work out in the long run.
