I think you need to work hard to improve the websites by add more wallet, option, and alternative.

In this sites you only list browser (online) wallet, mobile wallet for android/IOS, Desktop wallet and exchanges to trade.

I suggest to add paper wallet and hardware wallet, for bitcoin paper wallet [1] for Ethereum and other ERC-20 token paper wallet [2]

Hardware you can add trezor [3] and ledger nano [4]

For Bitcoin wallet is better to use electrum, wasabi wallet or Bitcoin core rather than trust wallet and exodus, trust wallet are closed source and exodus usually charge large amount fees.
