If you want to attract new users consider how you're writing to them (or the card owners even).It took to long to understand it for me. BUT BUT... if i do understand it correctly I think what you're doing is pretty awesome!! Honestly this is really quite great!

And it doesn't have to be pitched as some sort of competition between rental market. There are tons of owners that have cards sitting there not on the rental market and they may love to use this depending on how hard it is to set up (also an issue for rental markets). They're both filling a role some people just want something easier with less management no matter the ROI difference. And seems like this role is for new users so I'm hoping to see a really nice site that is pretty intuitive because I really want to see more players and burning the cards and giving them DEC is honestly an awesome thing.

What i don't understand yet is how you switch accounts... do you change the private key for each user cuz that's pretty cool.
