We need to get onboard more well known merchants to offer HC. It's a win-win situation for both parties. Users need to spend sats easily, merchants needs customers to pay in sats. These HC, yes, are custodial, but are more like a credit line open with that merchant. If you already are going to spend your sats from that channel with the merchant, make sense to use HC offered by the same. No need to be big channels, 500k - 1 M sats I think is enough to start.
