console.log(btcWallet.generate());

// Generate a random mnemonic string (12 words) and generate a wallet from it
const mnemonic = utils.generateMnemonic(12);
const walletFromMnemonic = new Wallet('eth');
console.log(walletFromMnemonic.fromMnemonic(mnemonic));

// Generate multiple wallets
const wallets = [];
for (let i = 0; i < 10; i++) {
    wallets.push(new Wallet('eth').generate());
}
