my previous wallet has been hacked by someone and that too was a trust wallet. today a friend of mine had to face to the same problem i faced. his wallet also was a trust wallet. why these trust wallets are being hacked?? isn't trust wallet safe??
Do you think it's
trustworthy only because they call themselves
Trust Wallet? Maybe the problem isn't in the wallet, it's in the people using them. Just because you were hacked, doesn't mean it's because of the client you used. It's possible to get your Trust Wallet hacked, but it's also possible to get Electrum, Bitcoin Core, or even a paper wallet "hacked" if they weren't set up properly, if you used a fake website, or a vulnerable system.
The safety of your coins greatly depends on you. It depends on what other software you use, what you do on the Internet, how good/bad your common sense is, etc.
You never mentioned what coins you have and do you even need a multi-coin wallet in the first place? If you only have bitcoin, there is no need for a multi currency wallet when you have standalone clients that are good and safe.
I have not used Guarda wallet before, but know that if a wallet is a web wallet and you can connect to it using a web browser, that means it is only just having a mobile app, it is not a mobile wallet, but a web wallet.
I have never used Guarda myself, but I know that it supports both desktop and mobile devices.
Guarda has connections with Atomic Wallet, and ChangeNOW, which have been known to selectively scam in the past. It's not a good option for your coins and tokens.
