Compare the first and last few characters of an address with what the recipient sent you. Copy and paste, never retype.
You never need to send a whole coin. Bitcoin divides into eight decimal places, and the smallest unit is called a satoshi, or “sat”.
A new transaction waits until a miner includes it in a block. Blocks arrive about every ten minutes on average. Each block added on top counts as one more confirmation, and each one makes the payment harder to undo.
Unlike a card payment, a Bitcoin send cannot be reversed or charged back once it is confirmed. If BTC goes to the wrong address, nobody — not EnertexWallet, not a bank — can pull it back.
