Due to the withdrawal design not being very user-friendly, other aspects such as deposit speed, customer service speed, and being regulated by the FCA are still considered good, so an overall rating of average is given. Description of the non-user-friendly withdrawal issue: The withdrawal method involves first refunding the principal to the original credit card used for deposit, which is fine. However, if that credit card is no longer available and another withdrawal method is desired, proof of the card closure must be provided. Over a year ago, I deposited $10, which was lost. This time, I deposited $50 and made a profit of $10. However, since I have forgotten which credit card I used for the $10 deposit over a year ago and whether it was closed, ThinkMarkets customer service stated that they cannot retrieve the credit card details used for deposit. This poses a problem because even if you have accumulated profits, you cannot withdraw them until the refund of the principal is processed first, as per ThinkMarkets' policy. Therefore, to withdraw the profits, you must recall which credit card was used for the $10 deposit over a year ago, contact the credit card company to request records of the deposit and proof of card closure, and submit this information to ThinkMarkets official. Only then can the $10 be processed through another withdrawal channel. After completing this process, the remaining profits can be withdrawn through another channel. This design is quite non-user-friendly. Note: Attached is a conversation record with ThinkMarkets official customer service for reference.
