The currency market has seen a large swing between the currency's rise and fall, but this swing has never included technology such as the Blockchain, especially the ico support operations that have generated a lot of money over the past years.
All those who attacked or disassociated with Bitcoin or digital currencies were never removed from the Blockchain technology, especially the banks that chose to deal with the technology for financial purposes.
Credit Suiesse Group AG and ING Greop NV launched a $ 30.48 million bond lending transaction in March. HSBC, one of the world's largest banks, has also completed major financial transactions using R3's Corda, and other companies that have developed Blockchain Technologies such as Lg, Oracle and Naver.
In South Korea, some applications have received a lot of attention to the decentralization of blockchain such as Naver and Kakao, as well as emerging companies such as Kodebox and CLC.
There are some companies and banks that have dealt with futures contracts for Bitcoin and this of course confers great legitimacy on the Blockchain.
