Why your balance is not exactly what you sent
Three ordinary reasons the credited amount differs from the number you typed, and how to tell which one applies.
You sent what looked like $100 and the balance says something else. Usually one of three things happened, and none of them is money disappearing.
The network fee came out of the transfer
On some sends, the fee is deducted from the amount rather than charged on top — especially when you choose to send your entire balance.
So 100 USDT leaves and slightly less arrives. Check the explorer: the amount actually transferred is shown there, and it will match what was credited.
The price moved
If you sent a volatile asset, the dollar value at the moment it confirmed is not the value when you pressed send. Bitcoin can move a percent while you wait for confirmations.
Stablecoins avoid this, which is exactly why people use them to move money rather than to hold a position.
The sending side took a fee
Exchanges usually charge a withdrawal fee on top of the network fee, and it is often larger. It is disclosed, but on a confirmation screen people skim.
Compare three numbers: what you typed, what the explorer says was transferred, and what was credited. The gap between the first two is the sending side; between the second and third is the receiving side.
Where BYCRYPTO sits
BYCRYPTO credits what arrives on-chain and takes no deposit fee, so the second and third numbers should match. If they do not, that is worth raising with the transaction ID.
Sending out is free until 31 December 2026 as well — only the chain's own network fee applies, which is the first gap, not the last.
