Let\u2019s Talk Bitcoin! is a long-running independent podcast on the ideas, people and projects powering the cryptocurrency narrative. On this show, we basically talk about everything other than the price. 

Since we started this conversation in early 2013, a whole world of blockchains and tokens has sprung up alongside bitcoin, and we talk about those too as real-world events help us see what\u2019s real and what\u2019s just clever marketing.
