It is possible to pay $150 on fees if your wallet is having trouble communicating with the blockchain, as it may be estimating higher and higher prices. However, it is important to make sure that you have enough ETH to pay for the gas, as the gas fee can be quite high. If you do not have enough ETH, it may be displayed as a high fee such as $150. To avoid this, try changing your RPC, as it may be mis-calculating the fee. If this doesn't work, it may be best to contact your wallet provider to see if they can help you resolve the issue.
