A central phenomenon in recent times is certainly the one that has affected the financial markets and in particular the advent of digital currencies. These have shaken the market, bringing many capitals into this new world. Let's analyze its structure better: a very important role is undoubtedly that of the technology that lies beneath the exchanges in cryptocurrency Blockchain in fact it is the infrastructure on which the ecosystem of exchanges is based and also what makes it safe to carry out them. This technology makes it possible to validate blocks of transactions by solving very complex codes by the nodes of the underlying network. These nodes are very advanced hardware formats scattered around the world, serving the "Miners", that through a complex of processing units with a great computational power, they are able to decode very complex data and thus validate the transaction packets. The application of this technology is also establishing itself at the basis of new uses thanks to the fewer economic resources necessary for its use and thanks to the safety it offers.
Between technology and speculation
Unlike the Blockchain of which the great experts speak very well, and on which new projects and related technologies are being developed, the cryptocurrency instead they were appealed with negative tones. The latter have been defined primarily as a means by which to launder money or in any case used by criminals for the most varied purposes. Thanks to the fact that the transactions are carried out in total anonymity, they offer a great way to cover money passes of any kind and for any purpose. Secondly, the cryptocurrency phenomenon has been blamed, and it is possible that it is, as a speculative bubble ready to burst. In the midst of these considerations, the ecosystem continued to develop, new ones were born, and their trends up to a certain time were very promising for those who had invested. If initially everything seemed to be going well with a constantly rising value, the black period for the world of virtual currencies was not long in coming. A very dramatic collapse occurred when major news reached investors. In particular the China has decided to ban these currencies from its market, the Korea had previously also taken a very strict direction towards cryptocurrencies (a decision which then changed in the opposite direction) and last but not least, the reaction of the SEC who has decided to regulate them. These are the news that most negatively shook the world of cryptocurrencies, leading them to a huge thud. 
A component to be taken into consideration in analyzing a similar trend is certainly the one that initially led cryptocurrencies to explode: the promise of maintaining theanonymity, mixed with safety. The news mentioned above undermines the very basis on which cryptocurrencies were born. It has been information, which has nipped investors and miners from below who have seen the financial paradise to which they had had access broken into. With the subsequent regulation it would have been increasingly difficult to realize the profits of such a large entity. This is perhaps "justified" by the nervous reaction of investors and the downward collapse of currencies.
When the BIGs come on the scene
There were also other aspects that have been a bit of a paradox in the events related to digital currencies. In fact, large investors have talked about cryptocurrencies in a really harsh way, and then recently turned around and invested. One of them is Soros which is at the head of a fund of about 26 billion, and which has recently decided to take part in investments in digital currencies. That his and others' was a move FUD (fear, uncertainty and doubt)? Speaking badly of an economic phenomenon by personalities who are considered to be of depth within the economic and financial sector, certainly has a relevant feedback on investors, thus creating fear, uncertainty and doubt in their investments. The fact that investors have hesitated and that the price of cryptocurrencies has gone down has led to the creation of very tempting speculative situations. It is no coincidence that i Rockefeller have recently entered the cryptocurrency market. On the other hand, Soros' move could be read in another way, referring to his statement dating back to some time ago. He alluded to the fact that this was an investment / speculation system characterized by too much volatility. After the main wave of settlement that saw for example the Bitcoin rise to an altitude of 20.000 and drop back to 6.000 in a very short time, and in the wake of the other currencies reacted similarly, it is possible that now the market is settling on less volatile and therefore less risky trends. This may be the reason why Soros has considered it profitable to invest in the digital currency market now rather than previously.
Will in contrast
On the other hand, anyone who has not absolutely detached himself from his point of view, up to now, is for example Warren Buffet who has been against investing in this new world from the very beginning. Also Joseph Stiglitz, Nobel laureate and former Chief Economist of the World Bank, does not have a very good conception on cryptocurrencies, according to which they will vanish as soon as they become "mainstream" and that it is only non-regulation that creates appeal. It is certainly probable that the phenomenon will slowly move towards a settlement, as it is equally probable that once the wave of enthusiasm has passed, investors will head towards new speculative frontiers, or return to the classic ones. But it is also true that something is starting to move around this ecosystem. In Germany, for example, trading in digital currency is being promoted through a new application that should make transfers safe and behind which there is the stock exchange:
“BISON will make cryptocurrency trading simple. It will be the first digital currency application in the world to be supported by a traditional stock exchange, ”said Ulli Spankowski, executive director of Sowa Labs.
It is far from easy to say which direction this phenomenon can take. Surely, for better or for worse, cryptocurrencies have given enormous visibility to a technology that could revolutionize the way information is stored, authenticated and transferred. It is not possible to discard the idea that cryptocurrencies can be used in the future in everyday transactions, considering the absence of commissions, intermediaries (until now) and timing / errors during transactions, limited if not zero. It is not even possible to discard the idea that they are considered in the future, only as a way like any other to invest and trade.
