I believe Howo has been working on Resource Credit delegations. Once it is ready it will be implemented in the new hard fork and should solve some of these issues. You won't need to delegate Hive Power to players or participants, but instead just delegate Resource Credits so they can easily interact with the blockchain. This will make it a lot cheaper to be on Hive. You won't need to buy Hive and build Hive Power, you will just get free RC delegation from apps or communities or lease them for small fee.
