5 Essential Podcasts for Entrepreneurs Serious About Cryptocurrency Your buyer offers to pay you with bitcoins. Cool, but how do you spend bitcoin?

Imagine that it's October 29, 2012. You've just closed a deal to deliver a service or a product worth $100. But instead of sending you the funds by Paypal, your buyer offers to pay you with bitcoins.

Few people had heard of bitcoins in October 2012, so probably you would have balked. But if you had agreed to accept to accept 1,074 bitcoins instead of $100-deal, and you'd kept the bitcoins, you would have $3 million today.

Cryptocurrencies have exploded in value to become a huge opportunity. Backed by blockchains, a unique way of tracking transactions and preventing fraud, currencies like Bitcoin, Litecoin and Dogecoin (based on an internet meme) are changing how people around the world pay for goods and services.

Cryptocurrencies allow buyers and sellers to transfer funds almost for free and almost immediately, without using big companies or a currency that's under the control of a national bank.

Cryptocurrencies are the most democratic way of doing business, and it looks now that they're here to stay, but they're also complicated and difficult to understand. They're unlike the dollars in your wallet or even the numbers in your Paypal account. Fortunately though, there are some easy places to listen, to learn and to put yourself in a position to make the most of the cryptocurrency opportunity.
