Yes, you can access your bitcoin wallet from anywhere. There are a few different ways to do this, depending on how you have set up your wallet.
If you have a web-based wallet, you can simply log in to your account from any internet-connected device. All you need is your username and password.
If you have a software-based wallet on your computer, you can open it up on any other computer or laptop with the same software installed. You will just need to enter your unique wallet address and password.
Finally, if you have a hardware wallet, such as a Trezor or Ledger Nano S, you can connect it to any computer or laptop via USB. Again, you will just need to enter your unique wallet address and password.
So no matter where you are in the world, as long as you have internet access or a USB port, you can always access your bitcoin wallet.
