In the blockchain space, one universal truth quickly becomes clear—storing large amounts of cryptocurrency on exchanges is risky. While you have login details for your exchange account, you don't technically own the coins in your dashboard.
This concept often feels counterintuitive to newcomers. You might wonder, "If I can freely send, receive, and trade coins and tokens in these accounts, who's to say I don't own them?"
Blockchain law has the answer: exchanges hold the private keys for all user accounts, making them the de facto owners of your crypto.
“Not Your Keys, Not Your Crypto!”
If exchanges aren’t ideal for storage, what is? The answer: cryptocurrency hardware wallets. Their key advantage is being "cold"—meaning your private keys never touch the internet. Unlike hot wallets tied to online servers, cold wallets keep keys offline, secured by physical hardware.
Centralized exchanges are prime targets for hackers. Unlike decentralized exchanges (DEXs), they require users to surrender control of their private keys. Hacks happen frequently, making it critical to avoid storing large sums on any centralized platform.
DIY Cryptocurrency Vault
Creating your own secure storage solution is simpler than you think—no expensive hardware required. With just a smartphone and a removable SIM card, follow these three steps:
1) Download a Mobile Cryptocurrency App
Install a trusted wallet app like CloakCoin Mobile Wallet (Android-only) or any other crypto app. You can always add more wallets later.
2) Remove the SIM Card
A phone without a SIM is harder to track. Unless someone knows your device’s unique IMEI number, your phone becomes virtually invisible.
3) Enable Airplane Mode
Disable mobile data by switching to airplane mode. To conduct transactions, connect only via password-protected Wi-Fi. Without cellular access, your crypto activity remains private.
This method works for any cryptocurrency app added to your phone. If your portfolio extends beyond CloakCoin, simply ensure your device has enough storage for additional wallets.
Why This Matters
Owning cryptocurrency means running your own bank—with 24/7 transaction freedom and no third-party delays. But with this power comes responsibility: you alone must safeguard your assets.
Whether you opt for a commercial hardware wallet or a DIY solution like this, the core principle remains: control your private keys.
