When we initiate a withdraw, there is a column of information from MA on the right side of the website:
The time frame between submission of a withdrawal request and payment is primarily due to the risk of chargebacks. The large majority of deposits are made via credit cards, while withdrawals are made directly to the account holder's bank account. Chargebacks can be submitted up to six months after deposit, but most frauds are discovered within two month. After 50 business days, the risk of chargebacks is minimal while giving MindArk time to perform internal security checks.
