By late 2010, the first of what would eventually be dozens of similar cryptocurrencies — including popular alternatives like Litecoin — began appearing. The first public Bitcoin exchanges appeared around this time as well.
“This is a legitimate technology–it’s going to expand,” he says, “My longer-term view is nowhere near where some of [my current] views are.” It could even perhaps hit $10,000 again, he says. But that will probably take a few years. For now, we wait and see.

It will impose a 10 percent penalty tax fee on sellers and redistribute five percent of this tax to other people who already own the cryptocurrency.
The long term positive coherence relationship observed between online metrics and price may be the result of another factor which we hypothesise could be technical progress. As a project makes technical progress, it is likely to have a community form around it over time, increasing online activity and also demand, and hence price, of the particular cryptocurrency. An interesting avenue of future work would be to consider the coherence between price and technical progress (via looking at each projects source code repository—these are available as cryptocurrency projects are generally open-source).
