USDT vs BTC for deposits — fee breakdown

[Blockchain Bruno]

Spent a weekend running deposits in both BTC and USDT (TRC-20) across three operators and figured I'd share the numbers because the "BTC vs USDT" question keeps coming up.

Methodology: identical CAD-equivalent amounts (~$100, ~$300, ~$500), deposited from a Wealthsimple-like exchange to each operator's wallet, recorded total fees end-to-end (network fee + exchange withdrawal fee + any operator-side deposit fee).

Short version: USDT on TRC-20 was cheapest in every single test ($1-3 per deposit regardless of size). BTC on-chain ranged from $4-12 depending on mempool conditions. BTC over Lightning was theoretically the cheapest at <$0.10 but only one of three operators supported it.

Full numbers below. On-chain or nothing.

$100 deposit: USDT-TRC20: $1.20 total. BTC on-chain: $6.80. BTC Lightning: $0.04.
$300 deposit: USDT-TRC20: $1.40. BTC on-chain: $7.10. BTC Lightning: $0.06.
$500 deposit: USDT-TRC20: $2.00. BTC on-chain: $11.40 (mempool was elevated that day). BTC Lightning: not tested, operator capped LN deposit at $200.

Conclusion: if your operator supports USDT-TRC20, use it. If they only support BTC, batch your deposits (one big deposit beats five small ones), or wait for a calm mempool day.

Riding the crypto wave on this one — USDT is the obvious answer for fee minimization, no question. The flip side that doesn't show up in your spreadsheet: USDT-TRC20 is centralized infrastructure (Tron) with a known KYC chokepoint. If Tether ever blacklists the address or the operator's address upstream, your USDT is frozen and you have approximately zero recourse.

BTC on-chain is more expensive but it's also genuinely yours until the operator credits the deposit. Not your keys, not your coins applies to stablecoins double.

Texas, USDT-heavy for both deposits and withdrawals because Bitcoin price volatility on cashout days is genuinely annoying. Bruno's data matches my experience almost exactly — USDT-TRC20 has been ~$1-2 every time for me regardless of amount.

For US players, USDT also bypasses the BTC price-volatility tax — if I deposit at one BTC price and lose half a session later, my remaining USDT is still 1:1 with what I'd cash out. The line's wrong, fade it doesn't apply to stablecoins, which is the whole point.

Vegas. I run poker buy-ins almost exclusively in USDT now for exactly this reason — buy-in and cashout are denominated in the same unit. No "deposited at $58k BTC, cashed out at $52k BTC" math at the end of the session.

The house knows what it's doing on this stuff, btw. Most operators internally convert your BTC deposit to a stablecoin balance the second it lands. They're not exposed to your BTC price risk; you are.

Cosign on USDT, but with a Whistler/Seattle caveat: when I'm on US wifi my exchange (Kraken US) charges a flat $5 USDT withdrawal fee regardless of network, which kills the TRC-20 advantage on small deposits. Same exchange Canadian-side has cheaper rails. Worth pricing your exchange not just the network.

One other note: Cloudbet specifically supports Lightning for BTC deposits which makes the on-chain fee question moot for small reloads. The other operators I've tried still want main-chain. BC mountains, US bankroll, three different fee structures depending on where my laptop is plugged in.

This data is the kind of thing this forum needs more of. Bookmarked. One small methodological note: were the mempool conditions on your BTC tests within one standard deviation of the rolling 30-day median? On a quiet week BTC fees can be sub-$2 too. Worth flagging the day so the reader can re-derive a current estimate.

The math is the math.

Danielle — fair callout, I should have included the mempool snapshot. For the record: tested on a Tuesday with mempool sitting around 110-130 sat/vB. Quiet by 2025 standards, busy by 2022 standards. I'll re-run on a sub-50 sat/vB day next month and update.

On-chain or nothing, and on-chain conditions are part of the spec.

Adding the legal angle, because of course. USDT specifically (vs BTC) has heavier compliance overlay in the US — Tether's freeze list and the implications for offshore operators are non-zero. I personally still use it but I never park more than a week's bankroll on an operator address. If the operator's hot wallet gets frozen for compliance reasons, your stablecoin balance is the first thing affected.

Show me the license, not the logo, AND don't leave your float on the table.
