<p>I am just finding out about deterministic wallets. I have read <a href="https://bitcoinmagazine.com/articles/deterministic-wallets-advantages-flaw-1385450276/" rel="nofollow noreferrer">here</a> that it is possible to derive the private key if one happens to have given out both master public key AND a child private key. </p>

<p>So if we want to give someone a key to send funds to, is there a better one to give out? Or can it be any, as long as we don't give out the other one?</p>
