AllianceDAO 联合创始人 QwQiao：传统支付体系网络效应强大，稳定币支付难以短期取代

Core Viewpoint - The prevailing belief that new payment channels like stablecoins could disrupt traditional payment systems due to high fees charged by card networks (up to 3%) is challenged by the reality that card networks earn a very small portion of these fees, with most rewards going to consumers to encourage credit card usage [1] Group 1 - Card networks like Visa and MasterCard benefit from a powerful network effect, allowing them to expand their networks at almost zero marginal cost [1] - Merchants bear the full cost of transaction fees due to their weaker negotiating position, which reinforces the dominance of card networks [1] - The small share of fees received by card networks is offset by the scale of their operations, making them one of the strongest examples of network effects in business history [1]
