A reliable broker must have insurance for the client's money. A good broker never makes it difficult for its clients to make payments, especially withdrawals. Brokers must accept common payment methods including bank transfers, credit cards, and electronic wallets like Skrill. Furthermore, the transaction fee must be positive and the processing time must be within a few days.

Payment methods should be checked out prior to deciding on which broker to choose as I agree that they ahve a considerable impact on the overall safety of the trading experience for the trader. From the types of payment methods that are accepted to the fees involved and whether it takes ages to process - they all matter. You also mentioned that it is important for a broker to be insured and that is so true as it gives more peace of mind to the trader.
