According to the daily economic news report, this year, the “blockchain” has repeatedly been on the hot search, frequently creating hot spots in the capital market, and related concept stocks that are “linked” to it have set off a few daily limit. On the one hand, blockchain technology is constantly being explored, and its application fields are constantly being broadened. On the other hand, blockchain, as a “frontier concept”, has also been used by some lawless elements in the process of entering the public life. A gimmick. Ordinary investors should always remember that the sky will not fall off the pie, do not understand do not touch. Don't be confused by the super-high income claimed by the unidentified project party, let alone report the luck and try to get rich overnight. Be wary of criminals using the "blockchain" name to implement fraud.
