Buy DOT on BiFu via Spot: deposit USDT on the correct network (TRC20, ERC20, or BEP20), transfer it to Spot, open DOT/USDT, then place a Market or Limit order. Fees are Maker 0.02% / Taker 0.05%. DOT powers Polkadot’s Layer-0 multichain network.

Buying Polkadot (DOT) on BiFu is straightforward. Deposit USDT, confirm the balance is available for Spot trading, open the DOT/USDT market, and place a Market or Limit order. Using USDT as the quote asset avoids fiat conversion delays—you trade directly on the spot order book with transparent fees.

Polkadot is a Layer-0 multichain network designed for interoperability. It connects independent blockchains (parachains) under shared security provided by the Relay Chain. DOT is used for staking, governance, and securing the network. As of mid-September 2026, DOT trades around $1.09–$1.12, with a circulating supply near 1.7 billion and a hard supply cap of 2.1 billion enacted earlier in the year.

Key points upfront

USDT networks: BiFu commonly supports TRC20, ERC20, and BEP20/BSC for USDT deposits. Always match the exact network on the sending wallet/exchange and on BiFu—mismatched networks can result in permanent loss of funds.
Fees: Current standard Spot rates are Maker 0.02% / Taker 0.05%. Check the live rate shown in the bottom-right corner of the trading page; promotions may apply to specific pairs.
Account routing: Spot trades draw from the available Spot balance. If your USDT sits in another section, use the Transfer function under Assets first.
Order types: Market for instant execution at the best available price; Limit to set your preferred price and wait for a fill.
Security tip: Double-check the deposit address and network every time. Start with a small test transfer if you are new to the platform.
