The Quiet Takeover: Why Bettors Started Choosing Tether

Five years ago almost every conversation I had about crypto betting started with “so, how much BTC should I move?” Today roughly half of them start with “what’s the cheapest USDT rail at your book?” That single shift — from Bitcoin-denominated betting to stablecoin-denominated betting — is the largest behavioural change I’ve tracked in the industry, and it happened faster than most analysts expected.

The numbers are striking. Bitcoin’s share of crypto iGaming stakes fell more than 17 percentage points during 2024. Tether picked up roughly 7.3 of those points on its own, with Litecoin and Ethereum splitting most of the rest. By 2025, CryptoManiaks data showed BTC dominance among crypto gamblers dropping from 88 per cent to 77 per cent in a single year — they called it “the monopoly cracking” and “Tether blowing up the market.” Altcoins overall climbed from 26.8 per cent of crypto bets in 2023 to about 47 per cent in 2024.

What drove the shift wasn’t preference for Tether specifically. It was the elimination of a third outcome from every bet. When you stake in BTC, you’re betting on the match and on BTC’s price between stake and settlement. That second bet is uncompensated — the sportsbook doesn’t pay you extra for taking on FX risk. Once bettors internalised that, stablecoins started looking less like a compromise and more like the sensible default.

What the Volume Data Shows: BTC Down, Stablecoins Up

Let me put some weight behind the trend lines because “altcoins are rising” is a claim that deserves numbers.

SOFTSWISS data from 2024 showed crypto Bet Sum — the total money staked — grew 18.7 per cent year-over-year while Crypto Bet Count actually fell 12.8 per cent. Average bet sizes went up, transaction count went down. The explanation came straight from the operator’s COO: Bitcoin’s sharp price appreciation in late 2024 led to a more conservative approach among players, who placed fewer but larger bets. “The sharp appreciation of Bitcoin in the final quarter of 2024 led to a more conservative approach among players towards crypto betting. At the same time, the increased value of Bitcoin resulted in higher average bet amounts, positively impacting the overall Crypto Bet Sum.” That quote is from Vitali Matsukevich at SOFTSWISS, and it captures the dynamic perfectly: when BTC rallied, bettors stopped betting it and switched to something more stable.

Tether’s overall on-chain volume across 2025 tells the same story from the macro side. USDT transfer volumes averaged around US$703 billion per month, peaking near US$1.01 trillion in June 2025. That’s an absolute scale of stablecoin flow that dwarfs retail sportsbook activity, but sportsbook deposits are riding that same wave. Operators integrate USDT because that’s where the user volume is going.

Interestingly, BTC remains the main on-ramp into crypto overall — over US$1.2 trillion in fiat-on-ramp volume flowed through Bitcoin between mid-2024 and mid-2025. Bettors often buy BTC first, then swap to USDT, then deposit to the sportsbook. The chain is: fiat → BTC → USDT → bet. Each hop adds friction, but the bettor still prefers to wager in USDT once the funds arrive. The implication is that stablecoin dominance on sportsbooks understates the full crypto-gambling pipeline, because BTC is the entry vehicle even when it isn’t the staking currency.

One last data point for context on why this matters to you directly: the average crypto bet size grew 1.4× in 2024, while the average fiat bet size didn’t change at all. BTC-denominated bets are getting larger precisely because they’re getting less frequent, while stablecoin volume keeps climbing. The volatility effect I’ll cover in depth in the piece on BTC price volatility and settled wagers is the mechanism behind both halves of that statistic.

ERC-20 vs TRC-20 vs Solana USDT: Picking the Rail

USDT isn’t a single thing. It’s a token issued by Tether Ltd that exists on multiple chains, each with different fees, speeds and sportsbook support. Picking the wrong rail can cost you more than the bet’s house edge.

ERC-20 USDT, the Ethereum version, is the original. It’s the most liquid, the most widely supported, and the most expensive to move. Transfer fees depend on ETH gas conditions — on a calm day, A$4 to A$8 per transaction; during congestion, A$15 to A$40. Settlement time is fast in wall-clock terms but sportsbooks usually want 12 to 30 confirmations, so figure a few minutes end to end.

TRC-20 USDT, the Tron version, is the bettor’s workhorse. Fees are typically under A$1 and often effectively free when you have enough bandwidth staked on the network. Transfers settle in about three seconds. The tradeoff is that Tron’s compliance reputation is shakier than Ethereum’s — many regulated-leaning books won’t accept TRC-20 USDT even though their users would clearly prefer it. It’s the default for retail bettors, and it’s cheap enough that small-ticket deposits actually make economic sense.

Solana USDT has grown fast during 2024–2025 because Solana’s transaction cost is genuinely trivial — fractions of a cent — and settlement is near-instant. Book adoption is patchier; as of 2026 you’ll find Solana USDT at roughly one in three crypto sportsbooks. It’s worth checking before assuming support.

USDC on Ethereum L2 — particularly Arbitrum and Base — is the version I recommend most often to readers who care about both cost and regulatory hygiene. Fees similar to Solana, confirmation times similar to TRC-20, and Circle’s compliance track record is meaningfully cleaner than Tether’s. The downside is slightly narrower book support and the extra mental load of bridging to L2 first.

The practical rule: match the chain to the book. Don’t pick the cheapest rail in the abstract and then try to force your sportsbook to accept it. Deposit to the wrong chain and you’re in the territory covered by wrong-network recovery, which is a lot of wasted hours at best and a write-off at worst.

Issuer Risk and Why a Stablecoin Is Not Risk-Free

A stablecoin is only as stable as the entity that promises to redeem it. This is the unglamorous truth most stablecoin marketing studiously avoids, and it deserves a clean explanation.

USDT is issued by Tether Ltd, backed by a reserve portfolio of US Treasuries, commercial paper, and other assets. The reserve composition has been subject to significant criticism over the years, and Tether has settled with regulators over past disclosures about backing. The current attestations show Treasury-dominant backing, but the company is based offshore and the audit regime is weaker than US banking standards. Historically USDT has held its peg to the dollar through multiple market stresses, with brief excursions of one or two cents during extreme events.

USDC, issued by Circle, has a cleaner regulatory profile — US-regulated, bank-held reserves, monthly attestations. USDC has also de-pegged, most notably during the Silicon Valley Bank failure in March 2023, when it briefly traded below 90 cents on the dollar before recovering. The de-peg was a function of reserve concentration at a single failing bank, not of Circle’s practices per se, but it’s a reminder that “stable” is a relative term.

Then there’s the compliance angle, which is where it gets less comfortable for crypto bettors. Stablecoins now account for roughly 63 per cent of all illicit cryptocurrency transaction volume, overtaking BTC as the preferred rail for sanctioned entities and money laundering. That statistic has a regulatory consequence: issuers like Tether and Circle have freezing functionality built into the contracts, and they do use it. If a sportsbook address you interact with gets flagged and frozen, your withdrawal sits in a wallet that the issuer has paralysed. I’ve seen one reader lose three weeks of recovery effort over a USDT freeze that was eventually lifted, but only after the sportsbook’s compliance team engaged directly with Tether.

None of this is a reason to avoid stablecoins — the upside of hedging volatility is real and measurable. It is a reason to treat “stable” as shorthand, not as a promise. Don’t park your entire bankroll in a single stablecoin issuer. Don’t treat a USDT or USDC balance as equivalent to a bank deposit.

When USDT Beats BTC for Actual Wagering

Stablecoin betting makes the most sense in three specific scenarios, and not really in any others.

Scenario one: the bet sits open for a meaningful stretch of time. Futures bets, outrights, multi-leg parlays that take weeks to settle. During that wait, BTC can move 20 per cent in either direction, and that move lands entirely on your P&L. A USDT-denominated outright on the NRL premiership settles for approximately the USD value you expected when you placed it, regardless of what BTC does in the meantime. For anything with a settlement horizon longer than a single match, stablecoins dominate.

Scenario two: you have a target bankroll in fiat terms. If you’ve said “I’m going to commit A$500 to sports betting this month,” a BTC bankroll won’t stay at A$500 — it’ll drift to A$430 or A$620 depending on the market. For discipline-minded bettors, a stablecoin bankroll keeps the account-balance number honest, which makes stop-loss thresholds and session limits actually hold.

Scenario three: you’re running a strategy where edge is thin. If your expected ROI on a betting system is 3 per cent, getting hit by a 5 per cent BTC move during a week-long settlement cycle can flip a winning system into a loss for that week. Stablecoins strip volatility out of the equation and let you see whether the strategy itself works.

Where BTC still wins: fast in-and-out live betting where the stake-to-settlement window is minutes, not weeks. During a live A-League match, BTC isn’t going to move meaningfully in the 80 minutes your bet is open. Add a favourable Lightning rail and the fee advantage over ERC-20 USDT is decisive. Also, many sportsbook welcome bonuses and reload promotions are BTC-only or BTC-favoured — if you’re farming promotions for EV rather than betting on form, BTC often pays more.

The last case is boring but real: if you already hold USDT in a wallet from DeFi or trading activity, don’t convert to BTC to bet. The conversion spread plus the cognitive overhead of managing two stacks is friction you don’t need.
