In the world of cryptocurrencies, we tend to think our savings are safe just because we see them in an application, but the reality is, if that application decides to close or block your access, you are left out. The good news is that there is a way to be the true sole owner of your money, and it&#8217;s called\u00a0<strong>self-custody<\/strong>.<\/p>\n<p>Don&#8217;t worry if it sounds complicated, our goal is for you to understand it. In this guide, we will explain what it is exactly,\u00a0<strong>why it is the most important step you can take to protect your financial future<\/strong>\u00a0and, most importantly, how to do it without complications.

It&#8217;s basically like having cash under your mattress or in your own wallet, instead of having it deposited in a bank account.\u00a0<strong>If the bank closes, your money stays with you<\/strong>\u00a0because you are the one who has the only physical key to the safe.<\/p>\n<p>For this system to work, the crypto world uses two tools: the\u00a0<strong>public key<\/strong>\u00a0and the\u00a0<strong>private key<\/strong>.<\/p>\n<ul>\n<li>The\u00a0<strong>public key<\/strong>is like your account number or your house address, you can share it with anyone so they can send you money.<\/li>\n<li>The <strong>private key<\/strong>, on the other hand, is the real key that opens that safe.<\/li>\n<\/ul>\n<p>Whether you have 10 BTC or just 100,000 sats,\u00a0<strong>only you can authorize transactions<\/strong>, because only you possess that secret key.\u00a0<strong>Without intermediaries giving the go-ahead, you are the one who decides<\/strong>\u00a0when and how to move your value.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-28270 size-full\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/10.jpg\" alt=\"bitnovo_self_custody_wallet\" width=\"1920\" height=\"1280\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/10.jpg 1920w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/10-300x200.jpg 300w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/10-1024x683.jpg 1024w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/10-768x512.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/10-1536x1024.jpg 1536w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/p>\n<p>In short,\u00a0<strong>only you possess the private keys that control your funds<\/strong>. If you don&#8217;t have the keys, you are not truly the owner of your assets. This philosophy is frequently summarized in the famous crypto phrase:\u00a0<strong>\u00abIf you don&#8217;t have your keys, you don&#8217;t have control.\u00bb<\/strong><\/p>\n<p>Now, the Office of Investor Education and Advocacy of the U.S. Securities and Exchange Commission has <a href=\"https:\/\/www.investor.gov\/introduction-investing\/general-resources\/news-alerts\/alerts-bulletins\/investor-bulletins\/crypto-asset-custody-basics-retail-investors-investor-bulletin-0\">published<\/a> a new Investor Bulletin that openly explains and legitimizes cryptocurrency self-custody.\u00a0<strong>\u00abWith self-custody, you control your crypto assets and are responsible for managing the private keys of any of your wallets. With self-custody, you have complete control over access to the private keys of your crypto assets.\u00bb<\/strong><\/p>\n<h3><span class=\"ez-toc-section\" id=\"private_keys_public_keys_and_addresses\"><\/span><strong>Private keys, public keys, and addresses<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>To understand how money moves in the crypto world without banks involved, imagine you have a smart mailbox at your front door. This is how these three concepts work:<\/p>\n<ul>\n<li><strong>Public key\/mailbox lock:<\/strong>It functions as your wallet address, similar to a bank account number. Anyone can send cryptocurrencies to this address. Anyone can use it to \u00abseal\u00bb an envelope and put it in your mailbox, but once the envelope falls inside, that lock is no longer useful for reopening it.<\/li>\n<li><strong>Address:<\/strong>It is a shortened version of your public key and is what you share without fear when someone says: \u00abgive me your address to pay you.\u00bb<\/li>\n<li><strong>Private key\/physical key to your mailbox:<\/strong>\u00a0It acts as a master password that allows you to authorize the transfer of funds. If you lose or expose this key, you lose control or ownership of your coins, possibly irreversibly. If someone asks you for your private key, it&#8217;s as if they were asking for the key to your house; if you give it to them, you are handing over total control of everything inside.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-28272 size-full\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/4-1.jpg\" alt=\"bitnovo_public_key_address\" width=\"1024\" height=\"575\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/4-1.jpg 1024w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/4-1-300x168.jpg 300w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/4-1-768x431.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>\n<p>Very important, here is the golden rule:\u00a0<strong>the private key is NEVER SHARED<\/strong>. If you entrust your private keys to a third party, you are actually granting them total control over your funds. As Andreas Antonopoulos famously summarized:\u00a0<strong>\u00abYour keys, your Bitcoin. Not your keys, not your Bitcoin.\u00bb<\/strong><\/p>\n<h3><span class=\"ez-toc-section\" id=\"self-custody_and_blockchain_digital_ownership_and_verifiability\"><\/span><strong>Self-custody and blockchain: digital ownership and verifiability<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The concept of a self-custody crypto wallet embodies the fundamental principles of blockchain technology, providing true digital ownership. This aligns with the decentralized nature of blockchain networks, where no entity has authority over users&#8217; funds.<\/p>\n<p>What does it mean to \u00abbe the owner\u00bb in this world? Essentially, digital ownership is your ability to sign. Imagine that every movement of your cryptocurrencies requires an unforgeable autograph signature. Thanks to self-custody,\u00a0<strong>you are the only one holding the pen, your private key<\/strong>. If you don&#8217;t sign, the funds don&#8217;t move; it&#8217;s that simple. No matter what a third party says, if there&#8217;s no signature, there&#8217;s no transaction.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-28296 size-full\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/13.jpg\" alt=\"bitnovo_blockchain_security_self_custody\" width=\"768\" height=\"526\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/13.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2023\/04\/13-300x205.jpg 300w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/p>\n<p>Indeed,\u00a0<strong>self-custody on blockchain gives you total control over your digital assets<\/strong>\u00a0by managing your private keys, without intermediaries, while blockchain provides an immutable and verifiable record.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"why_are_so_many_people_looking_at_self-custody_now\"><\/span><strong>Why are so many people looking at self-custody now?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>People are looking at self-custody now due to the desire for\u00a0<strong>absolute control over their funds<\/strong>, protecting it from potential hacks, data breaches, exchange bankruptcies, and even regulatory problems. Thus responding to the growing distrust in centralized systems, consolidating the power of money in individual hands.<\/p>\n<p>Let&#8217;s remember, several major exchange collapses, such as the case of FTX, which led to significant loss of funds by users.
