In my previous post about blockchain and cryptocurrency, I discussed why I thought Tesla was making such a substantial investment in Bitcoin and allowing the cryptocurrency to be used for car purchases in the future. The balance of its revenue stream, which comes from selling surplus Renewable Energy Credits (RECs), will dry up in the next several years as competing automakers can produce their own Zero-Emission Vehicles (ZEVs) and build up their own RECs with states that require them.

Allowing its customers to purchase vehicles entirely or partially with Bitcoin is potentially one way of differentiating Tesla from other auto manufacturers. But this in and of itself is not a sustainable business strategy. Perhaps Elon Musk has another, even wilder business plan for Tesla over the long-term — a plan just as crazy ambitious as building giant reusable space rockets that can land on their tails.
