Neha Narula: The future of money

There are actually people all over the world running this software, and we call them Bitcoin miners. Anyone can become a Bitcoin miner. You can go download the software right now and run it in your computer and try to collect some bitcoins. I can't say that I would recommend it, because right now, the puzzle is so hard and the network is so powerful, that if I tried to mine Bitcoin on my laptop, I probably wouldn't see any for about two million years. The miners, professional miners, use this special hardware that's designed to solve the puzzle really fast. Now, the Bitcoin network and all of this special hardware, there are estimates that the amount of energy it uses is equivalent to that of a small country. So, the first set of cryptocurrencies are a little bit slow and a little bit cumbersome. But the next generation is going to be so much better and so much faster. Neha Narula
