I wish to have more recommendation or articles to read concerning wallets and it's security values but during my research I was recommended to use electrum wallet but I was confused if electrum wallet is an exchange or a custodial wallet, therefore i need a good direction, clarification and update of suitable wallet from senior colleagues.
For security, avoid putting/investing your money inside exchanges. There are lots of scenarios where exchanges have been scammed and hacked in the past which puts an additional risks to your cryptocurrencies.
Non-custodial wallets generally are safer since you have complete control over your cryptocurrencies with all the security keys and features at your grasp. If I may, I also recommend hardware wallets where you can store your private key in a safety deposit box for maximum safety and less risks in the process.
