When first investigating Bitcoin in 2011 I was highly concerned with it's energy consumption for the sake of crunching arbitrary calculations. It's a huge waste of natural resources. This is one of the main reasons I have been a big supporter of Peercoin. Peercoin eliminates the need for massive energy consumption and dedicated server farms. Both of these features will be very important in the future. http://en.wikipedia.org/wiki/Peercoin http://en.wikipedia.org/wiki/Peercoin Bitcoin is a huge innovation, but it can be considered the first major crypto-currency. In the long-run, alternate solutions like Peercoin will play a larger role in the market. Full disclosure: I have investments in both Bitcoin and Peercoin.
