After years of leaving my Bitcoin on exchanges "for convenience," I finally got a hardware wallet. The peace of mind is worth the $50. This short glossary entry at https://paybis.com/blog/glossary/what-is-a-hardware-wallet/ explains exactly what a hardware wallet is, how it works (offline keys, PIN, recovery seed), and why losing the device doesn't mean losing your funds. If you hold more than you'd be comfortable losing, read this before you buy one. It's not complicated, and you'll sleep better.
