We recommend using TimeX exchange, developed by Chrono.tech. If you don't have an account on TimeX yet, sign up, log in, click the 'Balances' tab in the top right of the page and, if you already have Bitcoin or Ethereum, deposit them to your account. If you don't have any BTC or ETH yet, go to Deposit USD in your TimeX account and follow the instructions to top up your account using a credit card or bank transfer. Once you have BTC or ETH, you can use it to trade TIME on the TIME/BTC and TIME/ETH market. If you have USD on your account, remember to trade it for BTC or ETH first.
