The choice is mostly about what happens to your dollar value while the money is in transit or sitting on a platform. Bitcoin (BTC) can gain or lose value in an afternoon. USDT is a stablecoin that aims to track one US dollar, so its price risk is small, though it carries other risks.
This page compares the two for moving your own money. It does not tell you where to bet. Offshore crypto sportsbooks are unlicensed in the US: see are offshore sportsbooks legal.
Price swings while funds sit
If you deposit $1,000 of Bitcoin and your balance is held in Bitcoin, your dollar position moves with the market. A 2% move in an hour is $20 either way. Over a weekend of betting it can be far larger. Your bets are not the only thing that changes your balance.
With USDT the balance is meant to stay at about $1 per coin. Small deviations happen. You can win or lose on a bet without also taking a view on Bitcoin.
Some platforms convert your deposit into their own unit at the moment you send it. If so, the swing happens before the credit and you are exposed during the wait. Check the deposit page for how the balance is held.
Fees
Network fees do not depend on the amount you send, as covered in network fees explained. They depend on the chain and how busy it is.
| Bitcoin | USDT on Tron | USDT on Ethereum | |
|---|---|---|---|
| Typical fee (illustrative) | A few dollars, more when busy | Often around $1 | Under $1 to $10 or more |
| Fee paid in | BTC | TRX or energy | ETH |
| Cost of a $100 transfer | About 2% to 4% at $2 to $4 | About 1% at $1 | Highly variable |
These are examples, not quotes. Check the live fee on your wallet’s send screen. Fixed fees hurt small transfers most: a $2 fee on $100 is 2%, and on $1,000 it is 0.2%.
Speed
From the official docs: Bitcoin produces a block about every 10 minutes on average, and its developer guide advises at least six confirmations for high-value payments, about an hour. Tron treats a block as solidified once 19 or more active Super Representatives have built on it, which typically takes about a minute. See how crypto deposits work for the full chain table.
Speed matters for Bitcoin in two ways. You wait longer, and you carry price risk through the wait. With USDT on Tron, both the wait and the exposure are short.
The tax angle
The IRS treats digital assets as property, not currency. Its guidance lists these as dispositions: selling for dollars, trading one digital asset for another, using one to pay for goods or services, and paying a transfer fee with digital assets. Moving coins between wallets you control is not a disposition. Buying crypto with dollars is not either.
For betting, that means:
- Bitcoin: each time you sell it, swap it or spend it, you have a gain or a loss equal to the value received minus what you paid for it. If your Bitcoin rose between purchase and use, there may be a gain to report even if you only moved money.
- USDT: a swap into or out of USDT is also a disposal, but because it holds near $1 the gain or loss is usually a few cents on the dollar.
The rules for winnings themselves are in crypto gambling winnings. This page is general information, not tax advice. A tax professional can apply it to your return.
Issuer and peg risk for USDT
USDT is only as sound as Tether. Tether states that its tokens are pegged 1-to-1 and backed by its reserves. That is the issuer’s own claim. Its terms also give it the right to freeze tokens and to blacklist addresses holding them. A frozen address can stop your USDT from moving at all. Bitcoin has no issuer and no freeze function.
Peg risk is small but real. If the market doubts the backing, USDT can trade below $1 for a while, and a cash-out at that moment costs you the difference. Keeping only what you need in a stablecoin limits it.
A worked example
All figures are illustrative. You bought 0.01 BTC at $90,000, so your cost basis is $900. You want to move $1,000 into a platform.
Route A: send Bitcoin directly (and the platform holds BTC).
- Bitcoin is $100,000 when you send. 0.01 BTC is $1,000. A fee of $3 is paid out of your Bitcoin.
- Six confirmations take about an hour. During that hour Bitcoin falls 2%, so your $1,000 is now about $980.
- The wallet-to-platform move may not be a disposal by itself. But when you bet with it, convert it or cash out, the IRS treats that as a disposal: $1,000 received minus $900 basis is a $100 gain. At an assumed 24% rate that is about $24 of tax. Paying the fee in Bitcoin is also a disposal, with its own small gain or loss. Ask a tax professional how your own case is treated.
Route B: swap to USDT first, then send on Tron.
- You swap 0.01 BTC for about 999 USDT after a $1 spread. The same $100 gain applies, because the swap is the disposal. You pay tax on it either way.
- You send 999 USDT on Tron with about $1 network cost. It arrives in about a minute. The dollar value is steady throughout.
- Later, converting USDT back to dollars at $0.999 is a gain or loss of about $1 on $1,000.
Using USDT does not avoid the tax event. It changes the price exposure during the wait and the number of future disposals that carry large gains or losses. If you instead bought USDT with dollars to begin with, there is no embedded Bitcoin gain, and the only taxable events are small.
Which to use
Use the coin that your cash-out route and the platform both support on the same network. Compare:
- Price exposure: USDT lower, Bitcoin higher.
- Fees for your usual amount: compare live quotes.
- Issuer risk: only USDT has it.
- Your records: more disposals means more to track. See records to keep.
Common questions
Is USDT safer than Bitcoin?
It is steadier in dollar terms, and it carries issuer risk that Bitcoin lacks. Neither is safe in the sense of being insured or refundable if you send to the wrong address.
Do I owe tax when I send Bitcoin to a betting site?
It depends on how the transfer is treated, and this is a question for a tax professional. A transfer between wallets you control is not a disposition under IRS guidance. Paying with Bitcoin or swapping it generally is. See crypto gambling winnings.
Which cashes out to a bank more easily?
Both reach a US bank only after you sell on an exchange that lists the coin and network. USDT’s steadier price makes the dollars you get easier to predict. See cash out to bank.
