Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.

Ticker symbols used to represent bitcoin are BTC[b] and XBT.[c]:2 Small amounts of bitcoin used as alternative units are millibitcoin (mBTC), and satoshi (sat).

The successful miner finding the new block is rewarded with newly created bitcoins and transaction fees. As of 9 July 2016, the reward amounted to 12.5 newly created bitcoins per block added to the blockchain. To claim the reward, a special transaction called a coinbase is included with the processed payments.:ch. 8 All bitcoins in existence have been created in such coinbase transactions. The bitcoin protocol specifies that the reward for adding a block will be halved every 210,000 blocks (approximately every four years). Eventually, the reward will decrease to zero, and the limit of 21 million bitcoins[f] will be reached c. 2140; the record keeping will then be rewarded solely by transaction fees.
The U.S. Commodity Futures Trading Commission has issued four "Customer Advisories" for bitcoin and related investments.

Startup Polycoin has an AML/KYC solution that involves analysing transactions. Those transactions identified as being suspicious are forwarded on to compliance officers. Another startup Tradle is developing an application called Trust in Motion (TiM).

Lack of adoption and loads of volatility mean that cryptocurrencies satisfy none of those criteria. That does not mean they are going to go away (though scrutiny from regulators concerned about the fraud and sharp practice that is rife in the industry may dampen excitement in future). But as things stand there is little reason to think that cryptocurrencies will remain more than an overcomplicated, untrustworthy casino.
