If i create a paper wallet , i got a public key and private key. so From using public key we can send BTC from binance. whenever i need to send BTC to binance from paper wallet , How can i do?
With paper wallets you usually have only one receiving public address, just copy that and paste it in Binance exchange, but remember to choose Bitcoin mainnet, not their fake tokens on altcoins chain.
I don't understand why you would use paper wallet for withdrawing from centralized exchnage, unless you plan to hold this for long time, but keep in mind that this coins will be connected with your identity (Binance=kyc) if you don't mix them.
