Many specialists in economics and fans of Bitcoin and cryptocurrencies are constantly reviewing and predicting about the future of bitcoin. These opinions are published in social networks and media specialized in crypto news such as Cointelegraph, among others.
For some detractor currents “There is a very high risk of the collapse of bitcoin that, according to many economists, has a real value of zero. Bitcoin is now a drifting mine and almost all financial regulators warn against it »(December 2017).  As it is a system lacking any support, neither from governments nor from an economic or financial entity In the face of this eventuality, their owners will find themselves defenseless.
If bitcoin and other virtual currencies are a fiasco, will they accept their personal and non-transferable responsibility and will pay the costs due or, on the contrary, will ask for repairs, claim compensation and blame governments and regulators for an eventual failure? Because speculation often feeds on the excuse «No one prevented me» as an exculpatory clearance. The reverse of this fallacy is the natural tendency of the regulation to ignore the potential risks and go with the tongue out to stifle the damage when they have already occurred.

Bitcoin, at the end of 2017, exceeds and multiplies the thresholds that some experts in the currents of the traditional economy use to detect financial bubbles and collapse situations: speculative overvaluation and volatility. Other factors that are difficult to assess and that may condition or impede the viability of bitcoin would be the following, all of them in the midst of a major debt crisis and fiat monetary mass.

Some respondents said that its importance was analogous to that of the Internet.
The government recognizes that the technology associated with digital currencies offers considerable potential, allowing users to transfer value (or other information) quickly, efficiently and safely, providing a permanent record of what happened and without the need for a reliable third party supervise the process
With respect to the security of transactions made with digital currencies, the presentations highlighted the use of cryptographic algorithms as a way to transfer funds securely through the Internet and avoid the possibility of false payments or double spending of digital monetary units .
The presentations suggested a variety of possible applications for this technology beyond retail payment services. […] They described several other examples of technology use, including decentralized data storage solutions (using blockchain technology to store files securely and efficiently)

↑ A user will never reveal his private key to anyone. Since it is mathematically impracticable to obtain the private key associated with a Bitcoin address, only the person who knows its associated private key can have access to the bitcoins of that address. In this way, cryptography provides strong ownership control, similar to who protects your money safely so that it is not stolen.
↑ Generally, central banks increase the monetary base of national currencies to intentionally generate inflation above zero  in compliance with their mandate. This fact obliges its owners to lend this money to third parties in exchange for an interest, either through bank deposits or other financial assets, so as not to lose purchasing power. On the contrary, the proportion in which the monetary base of bitcoins increases is predictable and close to zero in the long term, which are generally necessary conditions to be able to maintain purchasing power  without having to lend the asset to third parties or depend on Deposit financial institutions.
↑ In software, the name «client» is due to the fact that it acts, precisely, as a client requesting services from other applications called servers, which take care of your orders. The programs that run on each of the interconnected nodes that make up the Bitcoin network act as servers, processing, validating and storing the transactions initiated by the client’s programs. Bitcoin Core software is a particular case, since it behaves simultaneously as a client and server.
