When you want to purchase Bitcoin, the cost will depend on the platform you choose. It is important to carefully consider the fees and charges associated with various platforms when deciding where to buy Bitcoin. Many platforms make money through a spread, which is the difference between the price at which they are willing to buy and sell Bitcoin. Some platforms may also charge a transaction fee, which may be based on the size of the transaction, the payment method, and the user's location. As an example, a few popular platforms add 0.5% to their quoted price for buying transactions and subtract 0.5% for selling transactions to create a spread. It is also possible that you may be charged a withdrawal fee to transfer your Bitcoin off the platform or a deposit fee to add funds to your account.
