I got a great gift from the blockchain, it's awesome!

My character is often very curious about new things, so I have been interested in Bitcoin as a cryptocurrency for a long time. At the end of 2013, when I saw a report on Bitcoin, I was attracted by its decentralization. I was attracted by blockchain technology, so I bought some bitcoins in February 2014, and I have kept it since then. Since Bitcoin is a digital currency, I was worried about network security, so I copied the Bitcoin wallet key in a small notebook, and also made a copy and stored it in the old laptop folder, thinking to myself This should be foolproof, and over time completely forget about it.

About a year later, my house was unfortunately visited by thieves. The thieves climbed in through the half-open window of my toilet and committed crimes, swept away all the cash in the house, and later found that even the small book that recorded the bitcoin information was missing, but This discovery came too late, because the laptop with the bitcoin key was sent to the recycle bin for my wife under the custom of year-end cleaning, so the bitcoins I owned have vanished.

But God really cares for me. I had nothing to do last night. I looked through the old letters in the e-mail box for many years. Among the more than 2,500 e-mails in the Gmail mailbox, I found a pile of old letters six and a half years ago, that is, February 2014. In the letter file of the month, there are several unopened emails. When I opened it, it turned out that it was a confirmation letter sent to me by the intermediary platform after I purchased bitcoin that year. This is a remarkable discovery.

That year, I bought bitcoin three times, the first time with 60 euros, the second time with 30 euros, and the last time with 90 euros, for a total of 180 euros, the price at that time hovered between 446 euros and 576 euros Fortunately, the intermediary platform is still alive, so I traced it to my account, and I actually had 0.3434 bitcoins, so I immediately looked at the price of bitcoin yesterday. , and the euro is about 11,000 yuan. In other words, the bitcoin in my hand is now worth about 3,780 euros, which is 25 times the quoted price when I bought it. Didn’t I earn 3,600 euros after deducting the cost? awesome!

I am delighted to receive this gift, and I also want to make some popular science here. In fact, the role of the blockchain is not purely to serve digital currency. In addition to asset transaction and preservation of value, its non-tamperable and traceable , openness and anonymity, etc., allow the blockchain to be used for many purposes. For example, Estonia, the world's most avant-garde digital kingdom, took the lead in implementing the national "electronic citizenship" measures. Pay taxes online, open a company, formulate contracts, verify certificates, check medical records, and participate in voting without having to work hard in different departments, which is time-saving, safe, and efficient.

Of course, there is no absolute good side. Many criminals use its anonymity to engage in illegal transactions to avoid police investigation. Therefore, blockchain is a very good technology. It must bring happiness to human life.
