Also i am confused between BRD and Electrum. Is BRD open source too ?
Their code is available on
github. But since I haven't ever used it, I can't say how secure it is.
so making it so simple and easier you have to use Google searching button, then Google will list the wallet to you and you have to install the application, But i will prefe you to use Binance or coinbase but other's are there.
You should never use google for finding a wallet. If you use google, there's a probability that you visit a fake website and download a fake wallet or malware.
Also, binance is not a wallet. It's an exchange.
