Cryptocurrencies: Evolution, growth and perspectives of Bitcoin.

The present work was carried out with the objective of knowing the behavior and evolution of Bitcoin, since its launch in the year 2009 until the first half of 2.018. The Bitcoin (BTC) is the first cryptocurrency launched on the market as a new means of payment option. The qualitative research initially included a literature review about the origin of its creation, growth, evolution and degree of acceptance within the market of new financial assets. It continued with the documentary review of its main characteristics, its legal and financial evolution, supported by secondary sources, especially in the reports of journals specialized in the subject and of investment and payment platforms. Then we proceeded to the explanatory modality where the advances of the currency were identified as the first decentralized cryptographic financial network in the world, as well as the specific experiences of its growth evolution that gave rise to the creation of the Bitcoin Foundation, strengthening the link between the currency and its acceptance as an innovative financial asset. The Bitcoin offers a new payment mechanism that has had a sustained growth and is generating a new financial relationship, where the low participation of intermediaries allows to obtain lower prices in transactions.
