Restoring a crypto/bitcoin wallet can be done with the phrase that we saved. Besides I doubt we can recover our Bitcoin wallet.
A wallet seed phrase or private key is key for your wallet recovery. If you have it, you can recover your wallet any time.
Another method is you will need a wallet file in backup and if it is an encrypted file, you will need a password to decrypt it and access your wallet private keys and bitcoins.
I really support your opinion regarding basic newbie matters. Know and be able to operate a Cryptocurrency wallet. Because it is very important for newbies to save their assets.
Before they can trade, they must have ability to store their bitcoin or cryptocurrencies safely. Because the advice is always "Don't use all money for trading" so the part is not used for trading, must be stored safely and not on centralized exchanges. People have to be able to secure their own wallets.
Trading, I think a good and safe thing for newbies is investment compared to trading. Trading is high risk, but also high return. Considering the volatile movement of crypto, trading carried out by newbies without experience and knowledge can result in big losses and potentially gambling.
Trading is risky and I really believe that hope to get rich with trading will cause massive loss. With trading, you can win big then lose big and you will need a lot of time to master trading and control your trading decisions.
