Bitcoin is gaining excitement and value, and fast. But it’s not just a new currency, it’s also a new technology. So whether you want to invest, spend, or just hold a conversation, there’s a lot of ground to cover.

This pair of courses will give you an understanding of the crypto space. OneMonth Bitcoin covers the concepts and technical workings of Bitcoin, one of the fastest moving investments today. Over 2 hours of lectures, you’ll learn to buy BTC on Coinbase, send and receive Bitcoin, and set up a secure Trezor wallet. Then, in the second course called OneMonth Blockchain, you’ll focus on the decentralized ledger system called blockchain. It’s what underpins all cryptocurrencies, and holds immense promise beyond crypto. But if you want to understand all the news and excitement around Bitcoin and other cryptocurrencies, you’ll want the grounding offered by courses like this.
