You need a couple of Waves coins in order to cover fees when buying TE Tokens.
You can buy Waves coins in all trading plattforms, such as Binance, Bittrex and Kraken. You can also do it in Waves Exchange. You just need two things:
1. Your Waves address where you would like to get your Waves tokens. Your Waves address is located in the top right corner when you are logged in the Waves Exchange.
2. BTC or any other type of tradable cryptocurrency in your account to exchange for Waves.
Click “Trading” in the top center of your Waves account, and you will see a page like this.
Choose a trading pair (for example Waves/BTC) from the list on the top left side of the page (marked with a green square in the image below) and the selected market will open. There is also a search feature where you can enter the name of what you are looking for.
In the Buy/Sell area, located in the bottom right corner (marked with a green square in the image below), select “Buy” and then select “Market order” in the dropdown menu. Enter how many Waves you want to buy, then the “Buy Waves” button will become clickable and you can make your transaction.
