Encrypting Your Crypto

Ledger Nano S
The moment comes when you realize there's real money in your crypto wallet and you start wondering about hackers and ransomware and all kinds of bad stuff.

Internet Computer (Dfinity)
Dfinity launched Internet Computer last week, and ICP, its cryptocurrency, already has a market cap of over $30 billion.
