I can understand why you would want to take extra precautions when it comes to your Bitcoin-related activities. It's always a good idea to prioritize security and privacy, especially with something as valuable as your digital assets.

Using a separate phone for Bitcoin-related tasks is definitely one way to enhance your security measures. Many people in the cryptocurrency space use separate devices or even dedicated hardware wallets for their crypto transactions. This helps ensure that their private keys are kept secure and prevents any potential malware or hacking attempts on their primary devices from compromising their funds.

Ultimately, the approach you take will depend on your risk tolerance level and how much value you have invested in cryptocurrency. However, I think it's always wise to err on the side of caution when it comes to securing our digital assets - especially given that we're still in an early stage of this technology's development where there may be some vulnerabilities yet undiscovered by bad actors.
