It is unlikely that we will ever see a period when only digital currencies will be used. For this, technical progress and the standard of living in most states must rise to very high levels. However, now we continue to observe wars with their inevitable destruction of economies and a decrease in the level of well-being of citizens, new diseases and epidemics, global climate change for the worse, which provokes new cataclysms like the recent earthquakes in Turkey and Syria.

States are able to issue and issue digital currencies only as a kind of their non-cash payments. Therefore, the cryptocurrency can only go in parallel with the fiat of the states and is not able to replace the national currencies of the states. As long as states exist, they will not allow crypto to surpass their fiat.

Most likely, the high price volatility of the cryptocurrency will always remain. Its volatility cannot fall so much as to even approximately approach the fiat of states in terms of level. Indeed, unlike other markets, the cryptocurrency market is not regulated, and the price of a cryptocurrency depends entirely on the relationship between supply and demand. In addition, in my opinion, with an increase in the price of cryptocurrencies, the amplitude of price fluctuations will also increase. We can clearly see this in the example of bitcoin.

The Chinese leadership is now very closely watching the course of hostilities in Ukraine and the assistance provided to Ukraine by the international community. I think that what they see, namely the cohesion of other states to provide all kinds of assistance to Ukraine, greatly weakens the military fervor of China to attack Taiwan. In addition, China is very dependent on technology and trade with the US and European countries. And they perfectly understand what serious sanctions will follow if they decide to attack Taiwan. All this is now being tested in Russia and in the future it may well be applicable to China in the event of such aggression.

Therefore, China is now very cautious in its statements and actions. The intrigue remains over the emergence of information that China may provide military assistance to Russia with drones and artillery shells. If this happens, it will become obvious that China is preparing to attack Taiwan. Most likely, this is a stuffing of the necessary information, and China wants to use it in its multi-way combinations to obtain certain benefits, and not to help Russia in this losing war.

Perhaps, in some cases, arms manufacturers are making some effort to ignite the flames of some next conflict and thus increase the demand for their military products.
  Now the biggest war is unleashed by Russia in Ukraine. But the Russian military-industrial complex can hardly be suspected of this. Although, who knows. In any case, even for Putin's closest circle, his decision to attack Ukraine with all his might was a big surprise. And Russia itself, as it turned out, was not prepared for a serious and protracted war. Under the sanctions, Russia's military industry cannot actually work normally. But for the military-industrial complex of the United States and other NATO countries, the war in Ukraine really sharply increased orders for their military products. So, if before this war the United States produced about 20,000 artillery shells per month, then by 2025 they plan to increase their production to 90,000 pieces. This also applies to the military equipment of the NATO countries, which have shown high efficiency in this war. Against the background of the fact that the demand for bad Russian equipment in the world will fall, the military factories of NATO countries are already loaded with applications for many years to come.

In Ukraine, the Verkhovna Rada also today, on February 24, adopted a law banning the use of buses with diesel and gasoline internal combustion engines on public transport routes from 2036.
From January 1, 2036, only electric buses, buses with internal combustion engines running on gas, as well as buses with a hydrogen fuel cell will be allowed on bus routes in cities of district and regional significance.
Ukraine is gradually bringing its legislation under the European one, as it wants to join the EU in the coming years. Apparently, this law also belongs to this category. But until then, the transition to cars will be gradual. So, from January 1, 2028, at least 50% of buses must be electric, methane or hydrogen. Diesel and gasoline engines will gradually become a thing of the past.

After the reduction of gas supplies from the Russian Federation and the embargo against Russian crude oil, on February 5, sanctions against Russian oil products came into force. Some analysts and market participants feared that the restrictions would lead to a shortage of diesel and other petroleum products, but this did not happen, as European states instantly and painlessly rebuilt the logistics of supplies from Russia to the Middle East and Asia.

Diesel deliveries in January already surpassed those of December, with the share of imports coming from the Middle East and Asia rising to 60%, a record for the last 7 years. Deliveries of Russian oil products to Europe now amount to only 282,000 barrels per day.

Thus, the European countries almost did not notice the refusal of Russian supplies. This was facilitated by an active search for alternative suppliers, a decrease in domestic consumption, as well as warm weather in the winter before, which made it possible to significantly increase fuel reserves in storage facilities.

Another Russian plan to freeze Ukraine by direct bombardment of the energy infrastructure and put pressure on the countries of Europe by sharply reducing gas supplies not only did not produce any result, but also led to the opposite results. Now Europe is almost completely united in support of Ukraine.

Only in the first version of MakerDAO, only ETH could be deposited as collateral. In November 2019, the project community decided to switch to a multi-collateral system — that is, to allow users to use different cryptocurrencies for collateral. USDC, WBTC, MANA, USDP, LINK, YFI, GUSD, enBTC, and MATIC can currently be pledged on MakerDAO. Also in July 2022, MakerDAO became the first DeFi protocol to accept shares of public companies as collateral.

With regard to the above rules for regulating stablecoins by the Central Bank of Israel, they are quite acceptable. So far, the main thing is that stablecoins, backed by the currencies of different states, are being legalized and will freely circulate along with their fiat.

CBDC will greatly increase the possibilities and efficiency of cashless payments. Therefore, the interest of citizens and businessmen in national CBDC will be. Such payments, unlike non-cash bank payments, will be almost instantaneous. At the same time, the Central Bank will be able to fully control transactions and, if necessary, block their completion. But in any case, the advantages of CBDC over bank non-cash transactions are obvious.

Now over 110 countries are working on the possibility of issuing their own digitized national currencies or CBDC.
CBDC is a full-fledged equivalent of cash, it does not depend on the ability of banks to serve it. It is issued in the form of a unique code, which is stored on a special electronic wallet. During transactions, funds simply move from one wallet to another, there are no intermediaries (banks or financial organizations) or their participation is minimal. However, in any case, banks will have full control over their CBDC through e-wallets.
In Ukraine, CBDCs should also appear using the ethereum platform. But it is still difficult to imagine how it will all work.

Since the time of Peter the Great (this is the end of the 17th, the beginning of the 18th centuries), in all the wars waged by the Russian Empire, and then the USSR, Ukrainians participated on their side, and this gave them additional power, since Ukrainians have always been distinguished by resourcefulness and the conduct of non-standard military actions and free spirit of Zaporizhsky Cossacks. Now, for the first time, Russia has launched a large-scale war against Ukraine at the state level, and it cannot and is not able to win this war, despite more than a tenfold superiority in manpower and equipment.
Some countries, such as Poland, may be ready to support Ukraine with their regular troops, but Ukraine has not yet asked for such help and, most likely, will manage on its own. True, in the ranks of the Armed Forces of Ukraine there are volunteers from various countries, mainly from the CIS countries, who, with the help of Ukraine's victory, want to overthrow their anti-people regimes.

Of course, the future belongs to alternative energy sources and the most significant place among them is solar panels, the production of which is getting cheaper thanks to new technologies. So, scientists from the University of Rochester were able to develop a new method to increase the efficiency of the solar cell material. Silicon is usually used as the basis for solar panel development, because it is found in abundance in nature and has an excellent ability to convert sunlight into energy. However, the researchers decided to use in the development of panels a forgotten, but not lost relevance mineral - perovskite - a source of titanium, niobium and a number of other elements. It is quite famous for its crystal structure. If we use perovskite instead of silicon in solar panels, then the energy efficiency immediately triples. Probably, and this is far from the limit.

If technologies continue to improve further, then hydrocarbon energy sources can be forgotten. Of course, oil and gas can be used in various industries, up to the food industry, but not on the current huge scale. Therefore, Russia in this regard will lose its former significance and greatness.

A tactical nuclear strike against Ukraine by Russia is generally pointless from all sides. Putin doesn't really care about the Russian-speaking population of Ukraine, who will suffer from its use on the front lines in Ukraine. Now, "liberating" the settlements in the Donbass, the Russian troops are deliberately destroying them almost completely so much that it is simply impossible to restore them, and the Russian-speaking civilian population is dying there in the first place. In order to fight further under conditions of nuclear destruction, Russian troops will need to have special protection, and there are very big problems in them and with conventional equipment.

Attacking the western part of Ukraine is like attacking NATO countries, since the radioactive contamination will spread to them as well. And Putin has already been unequivocally warned that they will strike back not only at Russia, but also personally at Putin in his bunker.

In addition, militarily, a tactical nuclear strike will not solve anything militarily. Ukraine will continue to defend itself under any conditions. But it will become clear to the world that Putin's Russia will need to be destroyed and the impending threat eliminated.

The question is not that Russia wants to trade on the international market without using the dollar. It is generally very difficult for her to trade now, since almost all of her banks are cut off from the SWIFT payment system. If Russia issues and uses its own CBDCs, this solves practically nothing, since trading using the digital ruble also requires the involvement of the banking structures of both trading countries. In addition, now other countries do not want to trade with the help of Russian rubles, since this is a currency that is falling due to a failed war. Therefore, Russia's CBDC is unlikely to be successful in the international arena. After all, this is the same non-cash ruble.

Russia's war against Ukraine should generally end this year with a victory for Ukraine. This will indeed serve as a powerful deterrent for China, because they saw that the world does not tolerate aggression and that less militarily strong states are capable of defeating the aggressor if the world unites and provides all possible assistance to the victim of aggression. Of course, the Chinese government would like Russia to take over Ukraine. Then against this background, China would have had a free hand with respect to Taiwan. But this will not happen thanks to the resilience of the Ukrainian people and their Armed Forces.

To have good growth opportunities, Dogecoin needs to have additional useful features. Because there are already a lot of coins on the cryptocurrency market without such functions, and there is little chance of counting on another hype due to some actions of Elon Musk. This coin is unlikely to reach the price of one dollar. There are many much more worthy cryptocurrencies in this market than Dogecoin.

This law bans the sale of new petrol and diesel vehicles in the EU from 2035. And this means that old cars running on gasoline and diesel fuel will continue to drive on the roads of the European Union for a long time to come. But the law itself is useful and necessary. The need to phase out gasoline and diesel internal combustion engines is evident due to the current rapid climate change. If the climate continues to change and many countries see this as an obvious danger, then the transition to electric cars may even accelerate. On the other hand, every year electric cars will improve and become cheaper. So this law in the EU, I think, will work in a timely manner.

Russia has been living under ever-increasing international sanctions for almost a year now, and this leaves an imprint on all aspects of the state’s activities, and above all its banking system, given that almost all Russian banks are now disconnected from the SWIFT international payment system. Therefore, they are looking for a way out of the difficult current situation that arose due to the military attack on Ukraine.
At the same time, if the emergence of CBDC in other countries is a completely new and relatively risky project, then in Russia it is doubly risky. And yet little is known about him. Even whether it will use blockchain technology. Of course, the digital ruble can be used in international settlements where it is difficult to do this due to the shutdown of SWIFT. But let's see how it will be in practice.

The Internet and new technologies open up new opportunities for most of us, including such a type of work as teamwork, but at home. But these changes cannot be called global. A much larger proportion of jobs still use the traditional approach to work because manufacturing and other activities cannot be done online. A part-time job existed before, just with the advent of the Internet, the possibility of communication in the process of work without personal presence has significantly increased. But this applies only to a certain part of society.

If Russia suffers a crushing defeat in the war on the territory of Ukraine, the likelihood of a Chinese attack on Taiwan will also noticeably drop. The Chinese leadership is already behaving much more cautiously, having seen how civilized states have united in helping Ukraine with financial, humanitarian and military support. If the world community had given the same support to Georgia back in 2008, when Russian tanks invaded the territory of this country, then Putin would hardly have dared to attack Ukraine. But even in 2014, when Russia seized the Ukrainian peninsula of Crimea, as well as parts of the Donetsk and Luhansk regions, the world community reacted very passively, which made it possible for Putin to continue military aggression.
