But I don't know about wallets. I don't know how to use wallets properly. Which wallet should I use to invest in Bitcoin? And what should I do?
I want to know about wallets.You can actually go through this thread thread to actually get understanding of wallet, although some of the wallets there are not highly recommended but just have a good read, the most recommended hot wallet is the electrum wallet
You don’t use a wallet to invest in Bitcoin; you use a wallet to store and safeguardyour Bitcoin, and the best wallet you can use and that’s recommended is an open-source wallet. You can go for electrum wallet, BlueWallet Electrum Wallet or BlueWallet, which are both mobile-friendly wallets and easy to use.
For mobile friendliness I will actually say electrum isn’t that mobile friendly I still prefer BlueWallet when it is for mobile device while electrum to me is the best hot wallet currently. Also it should be understand that electrum only supports android mobile devices and not others aside it.
Hot wallets can be connected to the internet and they are mobile friendly, just like the example Nwada001 gave you. While the cold wallets are not connected to the internet and they are designed for long term storage of you Bitcoin. They are also called Hardware wallets and Ledger and Trezor are the most common.
To add to this I will advice OP against going for any of the listed hardware wallets most especially ledger which has been under scrutiny for its wallet recovery, one of the most common hardware wallet usually recommended is the passport wallet. I will advice OP to look into cold wallet set up if he wishes to invest huge amount of money
