Take a made-up household to keep the numbers honest. Someone abroad sends 300 dollars home every month. That is 3,600 dollars a year. What matters is how much of it arrives and what the person at the other end can do with it.
A year of 300-dollar transfers
The World Bank's Remittance Prices Worldwide page puts the global average cost of sending money at 6.36 percent of the amount sent (Q3 2025 data, page last updated 18 August 2025). It is an average across 367 corridors, so a real corridor can sit well above or below it. Used as a yardstick it gives this:
Bank route Crypto to crypto
One transfer of 300 dollars about 19 dollars lost a network fee
Twelve transfers about 229 dollars lost twelve network fees
Left for the family about 3,371 dollars about 3,600 dollars, minus the fees
The network table on the USDT page linked below lists typical USDT transfer fees on Solana at 0.001 to 0.05 dollars and on Polygon at 0.01 to 0.10 dollars. At the top of those ranges twelve transfers cost between 0.60 and 1.20 dollars. The sender pays almost nothing in fees. The gap is the whole case for paying and receiving in a stablecoin. It only exists when both ends already hold one.
The same arithmetic scales in both directions. At 100 dollars a month the average costs about 6.36 dollars per transfer and about 76 dollars a year. At 1,000 dollars a month it costs about 63.60 dollars per transfer and about 763 dollars a year. A percentage fee punishes the households that send the most. A flat network fee does not care how large the amount is. That is why the comparison matters more to someone supporting a whole family than to someone sending pocket money.
The fee table is not the whole bill
Most comparisons stop there. That is where the useful question starts. A wire service converts twice, once into the local currency and once when the receiver takes the cash. Whatever happens to that currency after it lands is a cost too, even though no fee schedule lists it. A receiver holding dollar-pegged USDT does not carry that exposure while the money sits in the wallet.
The catch is what happens next. Rent, food and a phone bill are bought with something. If the only way to use the USDT is to find a stranger who will swap it for local cash, the saving leaks back out on the way down. I'd take the leak seriously. It is the reason many people who could receive crypto still don't.
What can she actually buy with it?
Part of the answer is gift cards that work like cash at a specific store. I run Genghis. On our USDT page the flow is short. You pick the card and enter an email address. You choose USDT and the network your wallet already uses. You send the exact amount shown. The code appears on screen once the payment confirms on the network. The page says the quote holds for about 20 minutes and the rate is not locked.
Because USDT tracks the dollar, the amount barely moves between the moment you see the quote and the moment it confirms, which is the property you want when the rate is not locked. Pay inside the 20 minutes and what you sent is what the card costs. If the window runs out you start a new quote, so it helps to have the wallet open and funded before you begin.
Two details save money. Only USDT on Tron carries a network cost on checkout ($3.53 on the page). The other nine listed networks carry none, so the network you pick matters more than the coin. Also cards are region and brand specific, so a card for a store in the sender's country will not work in the receiver's. Whoever buys for the receiver has to choose the card for the country where it will be spent.
Where this does not work
It needs a stablecoin on both ends. If the sender earns in a local currency, the first conversion is still there and the arithmetic above shrinks. It also needs a receiver who can hold a wallet safely. Cash needs such as rent paid to a landlord who wants banknotes still have to leave crypto somehow. A gift card covers the stores it is made for. It does not cover everything.
If you send money home, price one real transfer both ways this week before you change anything. Use your own corridor on the World Bank page and compare it with the network fee on the wallet you would use. The number you get is more useful than my example.
