This is a topic that everyone always wants to be right, both banks and those who defend technologies, in this case I think that both ways of managing money should always coexist.

Fiat money is necessary, because many transactions must be that way, and the most fundamental part of progress gives the way open to bitcoin and blockchain technology.

The tenology of Blockchain and Bitcoin offer new ways to pay for goods and services, it is a totally free, decentralized economy and you can achieve your financial freedom quickly, besides the transactions are very secure and secure, they represent more confidence when it comes to making transfers which are very large and that all banks always put problems to make them, through bitcoin, they are made and they are very fast, without problems and without danger that the money is lost, besides that to steal through the bitcoin portfolios has been almost impossible because to hack there is no technology to do it.

FIAT thefts in money if it is much easier and very feasible for many, there is less security and it must be in cash. I believe that this is why both are necessary, because in case of a munificent failure of electric power or internet service, simply the bitcoin and the technology is canceled.
