According to WuShuo, AllianceDAO co-founder QwQiao shared a post stating that the common belief is that new payment channels like stablecoins could disrupt traditional payment systems due to card networks (such as Visa, MasterCard, etc.) charging fees as high as 3%. In reality, the proportion of fees taken by card networks is very small. Most of the rewards go to consumers to encourage continued use of credit cards. Issuing banks bring users to the network through customers, acquiring banks bring merchants to the network through merchants, and Visa/MasterCard, while only taking a small cut, can scale their networks at almost zero marginal cost thanks to the effects of scale. Merchants bear all the costs because they are in a weaker position during negotiations. This is one of the strongest cases of network effects in business history. http://(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=54160
