I have a question that
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?
i am confused
You can send btc from a cold storage to binance/any other btc wallet without worrying too much about having your private keys exposed online with the help of your master pub key.
You just have to sign the transaction with an offline wallet then broadcast it online.
