Unless you have a million dollar checking account -- and that would be naïve, given it is only insured by FDIC up to $250K -- you can walk into your bank and withdraw everything you've got in there, checking and savings, though they will discourage you from doing so while you're at the teller cage. You will be taken to a manager, who will take you to a closed area, and happily give you your money if you insist on it being given. However, they will ask you to take a cashier's check instead. They understandably don't want you carrying that kind of money out of the bank where everyone can see you having done so.Sorry, Woody, but that just isn't right. The only thing I have to fear regarding cash is the potential -- very, very small -- for counterfeiters. Bitcoins, on the other hand, are an incredible scam. The difficulty with the bitcoin is their "production," which is unregulated and not at all done transparently. There is nothing to prevent a sudden surge in bitcoins being dumped by a creator, nothing to prepare you for a sudden surprise major cash-in, nothing guaranteeing you anything. These aren't banks. They are not brick-and-mortar stock exchanges. They are entirely web-based, and anyone who pays in legal fiat will most likely be left with nothing.
Bitcoins take advantage of this so-called "emerging digital market" by selling an "opportunity" to be part of the next "big thing." The creators are actually preying on the down economy and on people who are unreasonably trusting -- maybe for an amount they normally could afford to lose, but probably not -- that these exchange will fulfill their role. Maybe they do for a little bit, but just like a Ponzi scheme, a lot of new investors are losing money in unviable fluctuations while people in the know, or the technogeek-geniuses, are making a killing by "pretending" to get their digital blocks compromised. Think Mt. Gox. Only 46% of the pending transactions get refunded, if you're lucky enough to get a refund. Your money can be said to be "floating around in cyberspace," but it isn't. Somebody got it, and you'll never see it again.
Here's a major clue to the scam: Contact with these exchanges other than through their website is impossible. There are no email responses, no phone numbers for customer services, any complaints that do get to an actual location somewhere go unanswered, and nearly half the original "exchanges" have completely disappeared from the web.
