This feature is pointed out as being particularly inconsequential for credit-based ecash systems. Rug pulls, in the context of cryptocurrency and digital finance, refer to scenarios where the developers of a digital asset abruptly withdraw their support or investment, leading to a significant devaluation. The mention of it being a "complete non-issue" for credit ecash suggests that the structure or operational mechanism of credit-based electronic cash systems potentially mitigates the adverse effects or likelihood of rug pulls happening. This could imply a level of security or stability in credit ecash that is not present in other forms of digital currencies or assets, highlighting its resilience or different operational dynamics that protect against such fraudulent activities.
