It is ultimately up to you to decide whether to withdraw from Ankr BNB vaults or leave it there to receive claims later. However, it is important to consider the potential risks and rewards associated with each option before making a decision. If you decide to withdraw, you will have immediate access to the funds, but you will also be foregoing any potential claims that may be available in the future. On the other hand, if you leave the funds in the vault, you will have the potential to receive claims in the future, but you may be taking on additional risk if the value of the funds decreases or if the claims are not fulfilled. Therefore, it is important to weigh the pros and cons of each option before making a decision. Additionally, if you need assistance with filing a claim or need help with compensation, you can always contact Ankr for assistance.
