Not sure if anyone has a plan here, but I can share some thoughts.

I believe that B&C will bring lower costs for liquidity as the exchange default risk can be taken out. With the ability to provide more liquidity against the same cost volume would likely increase. Higher volumes would generate more fee generation on the blockchain. As you know every transaction will take place on the blockchain contrary to classic centralised exchanges which use off-chain tokens. You might do some simple calculations based on the number of transactions and volumes off Poloniex and translate that to on-chain transactions and related fees.

The demand would be typically from traders, but a new more anonymous type of user/trader would join us given that you don’t need to sign up for B&C. The BTC and probably the ETH volatility will always be there, the more the better as it justifies NuBits’ existence and will increase demand.

Time will tell how much new volume and fees will be generated by B&C for Nu. But Nu definitely has a common interest in making sure B&C succeeds.
