Is it illegal to charge the customer 3% credit card fee?

It's important to note that this rule applies to various industries, including but not limited to, credit card processing, shipping, and other services that involve the collection of fees from customers. Compliance with this regulation is crucial for businesses to maintain a positive reputation and avoid legal consequences.

In the context of cryptocurrency exchanges, such as BTCC, this rule may also apply to their transaction fees. BTCC, as a top cryptocurrency exchange, offers a range of services including spot trading, futures trading, and wallet services. It's essential for them to comply with relevant regulations and ensure that their fees are transparent and fair.

The regulation of surcharging practices is a crucial aspect of maintaining fair and transparent business practices. It is essential that companies adhere to the principle of not surcharging more than the actual cost of processing fees. This rule helps to ensure that consumers are not unfairly burdened with excessive charges.

Specifically, this regulation dictates that a surcharge cannot exceed a certain percentage of the total transaction value, typically 3% in the United States. This limit serves as a safeguard against businesses using surcharges as a means to generate additional profits, rather than simply covering the costs associated with processing transactions.

When it comes to BTCC's services, they offer a comprehensive platform for trading and storing digital assets. Their spot trading service allows users to buy and sell cryptocurrencies at current market prices, while their futures trading service enables traders to speculate on the future price of cryptocurrencies. Additionally, their wallet service provides a secure and convenient way to store digital assets.
