Edward felten bitcoin wikipedia
It is entirely possible that another cryptocurrency will displace Bitcoin due to technical improvements, but it seems very likely that a cryptocurrency of some type will be an important form of money in the coming years. Your Bitcoins are controlled by your secret key, so an intruder who gets your key can steal your Bitcoins. For example, Bitcoins can be archived on paper so you could scan it back into a computer or on a storage device that is locked up somewhere.
However, these are inconvenient. Many people rely on online wallets to protect their coins, but these create a risk of misbehavior by the wallet provider. There are larger concerns about privacy of Bitcoin transactions. On one hand, transactions must appear on the public ledger, which everyone can see, so people can see money flowing into and out of your wallet.
There has been a lot of research surrounding whether and how one might identify the owner of a particular key. The privacy issues connect to concerns about the use of Bitcoin for criminal purposes such as money laundering.
Law enforcement agencies have had some success in tracing the ownership of coins associated with illegal activity so that Bitcoin is not an easy safe haven for criminal money.
Nonetheless, this will continue to be an area of concern for governments and for legitimate Bitcoin businesses. To learn more about Felten's work, click here. Quotes from this article may be used without permission. Interested parties may also link to this story.
