1. The topic of blockchain and bitcoin has gone crazy recently

in fact, Mr. Xiao Zaojun paid attention to this very early. Last year, I wrote a popular science article about blockchain and bitcoin. At that time, the price of bitcoin seemed to be $3000, and many people suggested that I start. After thinking about it, I still didn't buy it

later, bitcoin soared and plummeted, peaking at $20000, and then quickly fell to $8000. I'm both sorry and glad<

today, I've also rerouted that article (with some revisions). I hope it will help you to know more about blockchain and bitcoin technology

in my opinion, whether you invest in bitcoin or not, whether you believe in blockchain or not, first of all, you should fully understand them

today, let's talk about blockchain and bitcoin

well, here's the thing -

these days, if you haven't heard of bitcoin, it's really out

when you see the glittering gold coin, is it a moment of spirit

in other words, bitcoin is not an ordinary fire nowadays. Some friends always come to ask Mr. Xiao Zaojun about it. Even when you take the subway, you can hear people around you talking about it<

bitcoin has been used for several times, and the most influential one is this:

children's shoes must be familiar, and indivial children's shoes are expected to be shocked

Yes, this is the blackmail window that popped up after computer poisoning when wannacry blackmail virus broke out in May 2017

the words in the blue box are the way blackmailers ask for ransom - "only accept payment in bitcoin", and others are not recognized. At the same time, the blackmailer also kindly tells you how to buy bitcoin

as a result, bitcoin, along with the blackmail virus, swipes the screen all over the world, greatly enhancing its popularity.

Recently, the concept of blockchain has made a comeback. Since February, the US House of Representatives has held two consecutive hearings on blockchain, upgrading blockchain to "revolutionary technology", and exploring its future application and impact on finance, commerce and government. At the same time, Russian President Vladimir Putin also said that Russia will focus on the development of blockchain technology to strengthen Russia's voice in the international competition in the field of cutting-edge technology. In China, more and more instries begin to pay attention to the field of blockchain technology, and this concept has also become one of the hot topics ring the "two sessions" this year

in today's surging tide of rejuvenating the army with science and technology, there are still many places for us to further explore the new technology of blockchain. Especially in the high-tech field where other people make "rules", we should take a long-term view, continue to innovate, digest and absorb the essence of blockchain technology, and strive to form a core competitiveness with independent intellectual property rights. At the same time, in the face of all kinds of temptations, we need to be cautious at all times, to see the risks and avoid losses, and never let the floating light of economic interests block our understanding of the nature and deep value of blockchain

4. Kaipu coin is a marketing coin, which is mainly promoted by the mode of direct selling or pyramid selling. This kind of currency is very popular in China, but it usually ends in a crash. Some of the main criminals will be arrested. Baichuan coin is the best example. Morgan money has done a better job in this respect, and few leaders have been arrested. This kind of money is not allowed to operate by the state. It can be said that it is a disguised form of pyramid selling
bitcoin, Ruitai coin, Laite coin and doggy coin are all mainstream digital currencies with their own application scenarios, rather than relying on marketing.

The way to distinguish the true and false of Mentholatum is as follows:

1. Look at the package, the package is intact, the handwriting is clear, and there is Mentholatum logo

Generally speaking, the fragrance of Mentholatum facial cleanser is light, and the one with strong fragrance is problematic

3. There is a 13 digit number on the package, which is the bar code of the commodity. You can find out what the commodity looks like after entering it on the Internet

4. The handwriting of false Mentholatum is not clear, which is the kind of font that can not be printed clearly, so the handwriting is fuzzy at first sight

The packaging of false Mentholatum was rough
