Making Money Stuff.

If I get a lot of Bitcoins, I will probably invest in a cold storage wallet. I'm not really sure how it works, but it's probably a USB-plugged piece of hardware that will give a beep when giving a bitcoin address and will store the amount of bitcoin in the hardware. I'm not really sure. I'm just a bit skeptical because when I clicked on a website Bitcoin wallet, it said that the environment is vulnerable so I really need to store only a small amount on that wallet and make sure I don't click on bad sites, and I should probably transition to a hardware Bitcoin wallet over time.
