Hi, I created a papper wallet (https://walletgenerator.net/?currency=Testnet%20Bitcoin#) and transfer some funds to the wallet A, but now I have only access to the private/public key.
What is the easier way to transfer my funds to a different wallet B (testnet too)?
I don't have an android with me, only iOS, macos and ubuntu.
Ideally, it would be nice an online wallet so I can import my private key and transfer the btc to another wallet.
