Electrum is the Bitcoin software wallet we suggest to use because it's safe and light. Available for Windows, Mac, Linux and Android. For Windows we recommend to use the portable version, which can also be installed on USB. The website is in English but the application is translated into all languages.
Metamask is a wallet software for the Ethereum network that we recommend because it allows you to connect to decentralized finance tools and interact with them by moving all your ERC20 tokens. Available as a mobile app for Android and iPhone and for PC as an extension of Google Chrome, Mozilla Firefox and Brave.
