ACH Transfer refers to the Automated Clearing House network, which facilitates electronic payments and money transfers between banks in the United States. In relation to cryptocurrency, ACH transfers are often used to move funds from traditional bank accounts to exchanges where digital currencies can be bought or sold.When someone wants to trade cryptocurrencies, they typically need to fund their exchange account. An ACH transfer allows users to transfer money directly from their bank account to the exchange without writing a check or using cash. This process usually takes one to three business days to complete.While ACH transfers are convenient, they involve banks and can come with limitations, such as daily or monthly transaction limits. Additionally, ACH transfers can be reversed in cases of fraud, which contrasts with cryptocurrency transactions that are generally irreversible once confirmed on the blockchain. Overall, ACH transfers provide a bridge between traditional finance and digital currencies, making it easier for users to enter the crypto market with familiar banking practices.
