Bitcoin transaction fees can get high on a busy day if you pay to get your transaction faster consideration. Paying the standard amount will usually work, but it can sometimes take hours for the transfer to complete, which is suboptimal if you’re trying to pay for something that only guarantees the price in Bitcoin for a certain period of time. That is been my personal experience anyway.
