This morning, a whale account claimed that its cryptocurrency account was hacked, stolen US $ 15 million in BTC and US $ 30 million in BCH, and the message was verified by the signature of the coin's founder. Yesterday, there was news that an Irish drug dealer printed a 46 million pounds Bitcoin address on A4 paper and put it in a fishing rod. As a result, the fishing rod was lost, and the two pieces of information lost a total of nearly $ 100 million in cryptocurrency . For these two messages, most investors still look at it from a ridiculous angle, but it also reflects several problems. Online storage addresses are not secure , including on the cloud and email. They are the targets of hackers. A stolen user is most likely attacked by a hacker through a mobile phone SIM card. In recent years, there have been too many incidents of hacking of exchanges and private user accounts. It is not an exaggeration to say that the cryptocurrency market has become a cash machine for hackers. There will still be some negative effects on the market in the short term. After all, it will also cause panic among some major currency holders, change the way of their storage addresses, and even withdraw cash. Although most of our small partners have not encountered such an incident, it is still worthy of vigilance. After all, more and more investors are now storing information online, but have not yet encountered it. It may be that poverty has protected us. That is, the three gourds on our account are not worth the hackers' intention to visit. The storage method of the Irish drug dealer looks ridiculous, but it is relatively safest. At present, the safest way is to copy the address on paper and put it in a safer place . As for the missing fishing rod, the authenticity needs to be judged by himself. Perhaps the police cannot dig the ground where it is buried. Go find out. It is also funny to say that we are involved in the most advanced technology in the world, but we still need to ensure the security of our accounts through the most traditional methods. Speaking of recent cryptocurrency trends, this week's market has brought a strong negative sentiment to the market, but we can jump out of short-term market sentiment and look at the market.It will be found that the current major source of negative factors is not caused by price fluctuations, but due to the rapid changes in prices in a short period of time , but this has not played a decisive role in the long-term trend. The trend line fell slightly, the 30-day moving average of the daily line has not yet broken, or it has not been officially broken, and the decline range from 10,200 US dollars to the current 9600, the adjustment range is only about 600 US dollars, which has a substantial impact on the overall trend limited.
