Once you have created your wallet, the next step is to register on a cryptocurrency exchange. Binance, Kraken, and Coinbase all offer user-friendly interfaces. First, you need to top up your balance using a bank transfer, credit card, or other cryptocurrencies such as Bitcoin or Ethereum. Then, select the desired trading pair (for example, NOT/BTC or NOT/USDT) and specify the number of coins to buy or sell. The trading platform will automatically select the best offers at the current market rate.
