While wallets are often described as a place to hold  or store bitcoins,  due to the nature of the system, bitcoins are inseparable from the blockchain transaction ledger. A better way to describe a wallet is something that "stores the digital credentials for your bitcoin holdings"  and allows one to access and spend them. Bitcoin uses public-key cryptography , in which two cryptographic keys, one public and one private, are generated. There are several types of wallets. Software wallets connect to the network and allow spending bitcoins in addition to holding the credentials that prove ownership.
With both types of software wallets, the users are responsible for keeping their private keys in a secure place. Besides software wallets, Internet services called online wallets offer similar functionality but may be easier to use. In this case, credentials to access funds are stored with the online wallet provider rather than on the user's hardware. A malicious provider or a breach in server security may cause entrusted bitcoins to be stolen. An example of such security breach occurred with Mt.
Physical wallets store the credentials necessary to spend bitcoins offline. Another type of wallet called a hardware wallet keeps credentials offline while facilitating transactions. Bitcoin was designed not to need a central authority  and the bitcoin network is considered to be decentralized. In mining pool Ghash. The pool has voluntarily capped their hashing power at Bitcoin is pseudonymous , meaning that funds are not tied to real-world entities but rather bitcoin addresses.
Owners of bitcoin addresses are not explicitly identified, but all transactions on the blockchain are public. In addition, transactions can be linked to individuals and companies through "idioms of use" e. To heighten financial privacy, a new bitcoin address can be generated for each transaction. Wallets and similar software technically handle all bitcoins as equivalent, establishing the basic level of fungibility.
Researchers have pointed out that the history of each bitcoin is registered and publicly available in the blockchain ledger, and that some users may refuse to accept bitcoins coming from controversial transactions, which would harm bitcoin's fungibility. The blocks in the blockchain are limited to one megabyte in size, which has created problems for bitcoin transaction processing, such as increasing transaction fees and delayed processing of transactions that cannot be fit into a block.
Bitcoin is a digital asset designed by its inventor, Satoshi Nakamoto, to work as a currency. The question whether bitcoin is a currency or not is still disputed.

Merchants accepting bitcoin ordinarily use the services of bitcoin payment service providers such as BitPay or Coinbase. When a customer pays in bitcoin, the payment service provider accepts the bitcoin on behalf of the merchant, converts it to the local currency, and sends the obtained amount to merchant's bank account, charging a fee for the service.
Bitcoins can be bought on digital currency exchanges. According to Tony Gallippi , a co-founder of BitPay , "banks are scared to deal with bitcoin companies, even if they really want to".

Bitcoin has been labelled a speculative bubble by many including former Fed Chairman Alan Greenspan  and economist John Quiggin.
Lee, in a piece for The Washington Post pointed out that the observed cycles of appreciation and depreciation don't correspond to the definition of speculative bubble. It's a mirage, basically. Two lead software developers of bitcoin, Gavin Andresen  and Mike Hearn,  have warned that bubbles may occur. Louis , stated, "Is bitcoin a bubble? Yes, if bubble is defined as a liquidity premium. Because of bitcoin's decentralized nature, nation-states cannot shut down the network or alter its technical rules.
