Thanks!
Hardware wallet is the most secure place to store bitcoin, such as Ledger Nano and Trezor. You can also use desktop wallet Exodus or web wallet Coinbase and Blockchain.info. These are a few best options.
These offline wallets are probably safe but there's a possibility that it might be hacked if we are too lazy not to keep our private key in the proper place. The most important is keeping the private key and seed of phrase to recover our wallet anytime.
I don't agree on the web wallet. Most of them have different issues.
Always bear this in your mind that if you're not holding private key/ seed phrase the bitcoin/altcoin you've stored is not belongs to you.
Use electrum wallet is the best option you install this on your clean laptop that not infected malware virus.
Here: https://electrum.org/
of holding up your own keys would be the best thing to be done rather than entrusting your funds into an online wallet which you dont posses your keys.
Electrum is the best choice not necessarily to install Core which is lot more heavier.
