The ticker symbol for Bitcoin Cash is sometimes displayed as BCC, or BCH, or XBC depending on the exchange. A satoshi is like a penny. The smallest divisible unit, with 8 decimal places. For the following example, we'll use BCH.
Transaction fees are calculated by the amount of data they contain. If you were to send a 100 byte transaction, the fee would be the same if you were sending $0.01 or $100,000,000. Luckily because the transaction capacity is improved from legacy Bitcoin, all transactions cost a fraction of a penny. The legacy chain reached $48+ fees at one point and many people were unable to use Bitcoin as a currency because the cost of using it sometimes exceeded what they wanted to spend it on.
