@LoyceV why do you trust it? Do you know the owners of it? Or have you tried generating keys without internet connection?
Also, I still don't get why I should never delete a wallet. Since I keep my private keys in safe places...
Wallet is the first thing to care about when one joins crypto but to choose which wallet to use for storing your funds, no one can tell you what you must do, they can only advise what you should do. In your turn, it depends on your understandings or preference or habit to choose which wallet you will use.
Fundamental rules:
- Prioritise to use non-custodial wallets if you can because you will have control on your private keys.
- Create your wallets offline because no one can steal your private keys at the time you create your wallet.
- Keep your computers as cleanest as possible because it will make sure no one can compromise your computer.
- Back up your wallet and test your backup for later recoveries.
Third party wallets, especially web wallets should be considered to use with some kind of risks because you don't know that ONLY you have control on your private key or the web wallet provider will have it too.
