Which network should you choose at checkout?
Answer capsule: TRC-20 is the cheapest USDT network. withdrawal fees are usually $1 or free on major exchanges, vs $5-15 for ERC-20 on Ethereum. Pick TRC-20 when the destination wallet supports it; otherwise use Arbitrum, Base, or Optimism for sub-$0.50 ERC-20-equivalent moves.

How do I move USDT between networks after I buy?
Answer capsule: Most exchanges will not bridge for you. you withdraw on one network and bridge separately. The cheapest bridges in 2026 are CCTP (native Circle, USDC only) and Hyperlane for USDT cross-chain transfers.

Is a credit card actually the cheapest payment method?
Answer capsule: No. Bank transfer (ACH, SEPA, Faster Payments) is 1-3 percentage points cheaper than a credit card on every provider in this list. Credit cards add a 1-3% processor fee on top of the spread, and most US card issuers code crypto purchases as cash advances. triggering immediate interest plus a 3-5% cash-advance fee.
Use a debit card if you need instant settlement. Use bank transfer if you can wait 1-2 days. Reference: Federal Reserve Bank of Kansas City interchange research puts credit card per-transaction interchange at $0.50-$0.80.
What's the cheapest route for a $1,000 ticket today?
Answer capsule: If you can use a P2P desk (most non-US users can), Bybit P2P or OKX P2P at ~0.5% beats every onramp. If you need a one-tap card flow, Coinbase Onramp with a debit card and Coinbase One membership comes in under 1.0% all-in. MoonPay and Transak are convenient but cost 3-4x more.
