The cryptocurrency market, dormant for nearly three years, made a powerful comeback at the end of 2020—ushering in a new bull run that pushed Bitcoin’s price close to $42,000. Although it has since pulled back to around $34,000, the surge has drawn significant investor interest. Many are now entering the market, aiming to capitalize on the momentum through active trading or long-term holding.
As digital asset adoption grows, so does the need for secure and user-friendly storage solutions. While many investors keep their crypto on exchanges, an increasing number are turning to hardware wallets—also known as cold wallets—to safeguard their assets from hacks, exchange failures, or fraudulent activity. These offline storage devices offer enhanced security while maintaining accessibility.
Among the rising stars in this space is CoolWallet S, developed by Taiwan-based fintech startup CoolBitX. With backing from Taiwan’s National Development Fund and Japan’s financial giant SBI Group—invested twice—the company has gained global traction, selling over 180,000 units worldwide.

Frequently Asked Questions (FAQ)
Why do I need a cryptocurrency hardware wallet?
A hardware wallet keeps your private keys offline, protecting them from online threats like hacking or phishing. Unlike exchange wallets, where you don’t fully control your assets, a hardware wallet gives you complete ownership—essential for long-term security.
What happens if I lose my CoolWallet S?
Your crypto remains safe. The lost device cannot pair with unauthorized phones, preventing access. You can restore full control using your 12–24 word recovery seed phrase on a new CoolWallet S or compatible wallet.
Can I earn interest on my crypto with CoolWallet?
Yes. Through the X-Saving feature in the Marketplace App, users can generate passive income via AI-optimized trading strategies across multiple exchanges—offering stable returns with low risk exposure.
Is CoolWallet S compatible with other wallets or apps?
While designed for use with the official CoolWallet App, it supports standard BIP39/BIP44 protocols, allowing interoperability with many third-party services and DeFi platforms.
Does it support newer cryptocurrencies and tokens?
Absolutely. In addition to BTC and ETH, CoolWallet S supports all ERC20 tokens and major altcoins, ensuring future-proof usability as the crypto ecosystem evolves.
How does encrypted Bluetooth ensure security?
The wallet uses end-to-end encrypted Bluetooth Low Energy (BLE) communication. All transaction data is signed inside the secure chip and transmitted only after user confirmation—making man-in-the-middle attacks virtually impossible.
Final Thoughts: Security Meets Simplicity
As Bitcoin reenters the bull market spotlight, protecting your digital assets becomes more critical than ever. With rising valuations comes increased targeting by cybercriminals—and reliance on exchange custody poses real risks.
Hardware wallets like CoolWallet S offer the ideal solution: military-grade security wrapped in a sleek, portable design with smartphone convenience. Whether you're a new investor or a seasoned holder, taking custody of your private keys is the smartest move you can make.
