Стейблкоины в платежных системах
Стейблкоины — криптовалюты с pegged value к fiat (обычно USD). Растущая доля в crypto-iGaming.
Типы stablecoins
Fiat-collateralized: USDT, USDC, BUSD — bank reserves. Crypto-collateralized: DAI — overcollateralized ETH. Algorithmic: UST (crashed 2022) — algorithm-based supply. Реgulated bank-issued: emerging (Paxos, Circle). Different risk profiles.
Advantages для iGaming
No volatility: player deposits $100 USDT, играет $100. Fast: transactions за seconds. Low fees: <$1 на Layer 2 (Polygon, Arbitrum). No chargebacks. Global: works everywhere. Alternative to banks для restricted regions.
Chain considerations
Ethereum mainnet: expensive gas ($5–50). Tron: cheap ($1), high volume USDT. Polygon: L2 Ethereum, cheap, fast. Solana: fastest, occasional outages. BSC: dominance in Asia. Support множественных chains для UX.
Regulatory
MiCA (EU 2024): specific rules для stablecoins. Reserves auditing. Redemption rights. Some restrictions в crypto-iGaming licensing. USDT scrutiny над reserves. USDC — regulated в US. Prefer regulated stablecoins для serious operators.
