If you want to use Bitcoin, you will need to have some kind of wallet. Here is some information that may help you to know what bitcoin wallet to use for your Bitcoin holdings. While there are loads of options, there are two basic types of wallets: hot wallets and cold wallets.
To actively use your Bitcoin, you will want to opt for a hot wallet. Hot wallets are connected to the internet all the time, so they are really simple to use for sending and receiving Bitcoin. Additionally, hot wallets tend to be free, and work on both PCs and mobile devices.
For larger holdings, a cold wallet makes more sense. Unlike a hot wallet, a cold wallet is only connected to the internet when you choose to make transactions, and is generally a dedicated piece of hardware.
One of the leading cold wallet manufacturers is Ledger, and there are other manufacturers that also make good products. If you want a hot wallet, there are many good options. Coinbase offers a free wallet as a stand alone product, and MetaMask is a great wallet if you want to use Ethereum.
Do a little research, and find the best wallet for your needs.
