Here’s how it works: Say Alice wants to transfer one bitcoin to Bob. First Bob sets up a digital address for Alice to send the money to, along with a key allowing him to access the money once it’s there. It works sort-of like an email account and password, except that Bob sets up a new address and key for every incoming transaction (he doesn’t have to do this, but it’s highly recommended).

searching for a good crypto exchange (wallets included) to trade altcoins. important for me: lot of tradeable altcoins, buyable altcoins with other altcoins, low fees, withdraw & user friendly interface.. any suggestions? thanks in advance
Thanks for this, so my story: I’m new and have been using Coinbase then suddenly was told I need to verify ID to continue buying. I’ve tried several times but have been unsuccessful, most likely because I recently moved from California to New Mexico. And as everyone knows their customer service is virtually non existent. So I’ve been trying to sign up with several other exchanges but keep getting told they don’t do business in New Mexico. I guess I’ll just keep trying exchanges until I don’t get rejected…unless you know of ones that do business in New Mexico.
Although this theory is a popular way to justify inflation amongst central bankers, it does not appear to always hold true and is considered controversial amongst economists. Consumer electronics is one example of a market where prices constantly fall but which is not in depression. Similarly, the value of bitcoins has risen over time and yet the size of the Bitcoin economy has also grown dramatically along with it. Because both the value of the currency and the size of its economy started at zero in 2009, Bitcoin is a counterexample to the theory showing that it must sometimes be wrong.
One estimate of the bitcoin network’s total energy consumption, the Bitcoin Energy Consumption Index, is up to 55 terawatt hours. A terawatt-hour would be 1,000 gigawatt-hours. The orders of magnitude just keep piling up.
Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work.
Fraud Risk: While Bitcoin uses private key encryption to verify owners and register transactions, fraudsters and scammers may attempt to sell false bitcoins. For instance, in July 2013, the SEC brought legal action against an operator of a Bitcoin-related Ponzi scheme.
Bitcoin has captured America’s imagination. Whether or not the cryptocurrency will ultimately turn out to be a good investment or just a passing fad remains to be seen. Indeed, in the past several months Bitcoin prices have enjoyed a run-up that makes the 1999 tech bubble look staid by comparison. That excitement — the promise of sudden riches or sudden ruin — has a lot of people wondering how a bitcoin investment actually works.
It is not possible to change the Bitcoin protocol that easily. Any Bitcoin client that doesn’t comply with the same rules cannot enforce their own rules on other users. As per the current specification, double spending is not possible on the same block chain, and neither is spending bitcoins without a valid signature. Therefore, it is not possible to generate uncontrolled amounts of bitcoins out of thin air, spend other users’ funds, corrupt the network, or anything similar.
