Bitcoin wallets need to be kept safe and secured, and encrypted. Huge amounts of Bitcoin should not be stored in clouds, stocks and markets. Do not keep a backup copy of your wallet unsecured. Having good and updated antivirus software on a PC with a Bitcoin client and fully updated OS and third-party software is essential. Or, as Brandt said:
Bitcoin needs its own version of the Pinkerton men, bonded and certified professionals whose job is specifically to safeguard the storage and transfer of bitcoins, and ensure that exchanges are performed fairly. I guess it would have to be something akin to the Nevada Gaming Commission, with the rights to waltz into a bitcoin exchange data center and take a look under the hood at any time. I guess it still kind of feels like funny money, but at a little over $1000 per bitcoin in today's prices, I personally would need more assurances than just a promise to do no evil, and a handshake.
Government, too, needs to step up to the plate. The Senate Committee on Homeland Security and Governmental Affairs has been alerted of the emerging threat and criminal exploitation of virtual currency systems and has held hearings with experts to discuss the concerns, particularly involving regulation, surrounding crypto-currencies.
