How to Buy Polkadot (DOT) with Tongtong Coin (TTC)

To buy Polkadot using Tongtong Coin, first, find a cryptocurrency exchange that supports the DOT/TTC trading pair. Create an account, verify your identity, and deposit your TTC into your exchange wallet. Locate the DOT/TTC pair on the trading platform and place an order to exchange your Tongtong Coin for Polkadot. If the DOT/TTC pair is unavailable, you can first exchange Tongtong Coin for a stablecoin like Tether (USDT) or a fiat currency, then trade that for Polkadot. Be mindful of potential exchange fees, which vary by platform and can affect the total cost of your transaction.
