Option 2: Secure and Customizable
Safe, but more complicated. You should rent a server and install an antidetect browser on it (e.g., AdsPower, Dolphin, etc.), customize it (proxies, Metamasks), and open your profiles. We will advise you and help with customization if necessary. After you open the profiles, we will start our work. In this case, only you will have access to the private keys, and if the antidetect browser profile closes, only you will be able to open it.
