Running a hub could end up being expensive as you need a massive amount of "collateral" to lock in your channels. A hub is rather worthless if it only provides $1 channels to all its "subordinates". If you have a huge "bank of america" hub connecting to hundred of thousands of entities through large channels on one side and a small "mylightninghub.io" with a dozen of people through $10 channels you better hope that they're extremely competitive on fees to make up for it. It's almost exactly like the credit card business currently. If I come to you and tell you "Here's the SimiasCard, it has extremely low fees and great advantages! But you're limited to $5 a day and it's basically accepted nowhere." Would you take it?
