All sounds like great work planned for this year! A DEC system would be awesome. It's a pain getting Hive to transact when not active on the Hive blockchain anymore.
- Renter only when needed so not many.
- No preference.
- Is it possible to have a list of bot accounts and have owners choose to not rent out? Or have a bot account list, and owners can rent out cheaper to real players not on the bot list? I would make more cards available for rent if knowing they're supporting real players and not bots.
