Many cryptocurrencies are capatilizing on the pull of proof of stake.  Can and should the bitshares exchange market itself towards investors, as well as traders?

There is talk about bringing back the "earn x% interest on anything."

What about as an alternative or a complimentary system we utilize a decentralized proof of stake system? 
We bring in cryptocurrencies with proof of stake onto the bitshares exchange.  Clients/investors/traders receive open.versions.  The collective mass of these cryptocurrencies are staked in open decentralized wallets; the accumulated weight give the decentralized stake greater rewards.  The minting of cryptocurrency through this process is then distributed back into the wallets of the clients/investors/traders.

This would give investors another great reason to place their cryptocurrencies with bitshares.  Easy hassle free staking, allowing those with even a small stake to collectively mint. 

Just an idea I thought I would share.
