FAQ — Buying with USDT or USDC (stablecoins)
Stablecoins are the fastest and cheapest option. Here is how to use them to buy your cards.
Why is USDT the recommended method?
USDT (Tether) is pegged to the US dollar: no volatility between order and payment. On TRON (TRC-20), fees are essentially zero (~€0.001) and confirmation takes seconds. Unbeatable for user experience.
What is the difference between USDT TRC-20, ERC-20 and SPL (Solana)?
Three different networks hosting the same token. TRC-20 (TRON): fees ~€0.001, 3s confirmation. ERC-20 (Ethereum): fees €1-5, 15s confirmation. SPL (Solana): fees €0.01, 1s confirmation. Pick the one where your USDT already sits.
And USDC? Any difference from USDT?
USDC is an equivalent stablecoin issued by Circle, considered more transparent and more regulated. For our use, USDC and USDT are interchangeable. If you have the choice, USDC offers slightly stronger guarantees.
Can a stablecoin de-peg from the dollar?
It has happened briefly (USDC in March 2023 during SVB, USDT a few times). Risk is low over short transactions like ours. We convert received funds immediately to minimize exposure.
Are stablecoins regulated in Europe?
Yes. The MiCA regulation classifies stablecoins as EMTs (Electronic Money Tokens) and imposes strict rules on issuers. USDC is MiCA-compliant; USDT is adapting.
How do I get USDT easily?
Via an exchange (Kraken, Coinbase, Bitstamp), a P2P service (Paxful, Bisq), or by converting other cryptos. Once acquired, transfer them to your personal wallet to pay us.
