**The U.S. Senate held a special hearing on virtual currencies. **

**The important views of Giancarlo, Chairman of the U.S. Commodity Futures Trading Commission (CFTC) are as follows:**

1. It is recommended to adopt a “do no harm” registration process for distributed ledger technology (blockchain), virtual currency companies and related start-ups.

2. Bitcoin cannot be ignored when mentioning blockchain. Without Bitcoin, there would be no blockchain.

3. Blockchain has a huge range of applications, and the connection between blockchain and virtual currency can promote safe payments.

4. Agree that ETF funds will reduce the volatility of virtual currencies.

5. He believes that policymakers should respect the enthusiasm of the younger generation for virtual currencies, and at the same time there should be sufficient legal and regulatory provisions to prevent people who attempt to abuse personal interests.

**The important points of Jay Clayton, Chairman of the U.S. Securities and Exchange Commission (SEC) are as follows:**

1. Believes that unregistered ICO is illegal and denies that it has ever approved or will approve ICO.

2. ICO has nothing to do with the blockchain itself. Purchasing an ICO does not mean investing in the blockchain. Currently, there are many problems in the virtual currency market and ICO, mainly due to the lack of supervision and the fact that many ICOs are illegal.

3. Blockchain may reduce costs in the economy, and I hope people can pursue the development of blockchain.

4. He doesn’t know the reasons behind the fluctuations in Bitcoin and other virtual currencies, but it is certainly different from what drives the U.S. dollar.

5. The SEC may work with the Treasury Department and the Federal Reserve Bank to request further legislation to protect investors; Congress may need to change financial laws to better regulate virtual currencies.

The two chairs believe that current licensing rules vary from state to state and that the policy may need to be revisited in favor of establishing a new, more reasonable federal regulatory framework. When asked whether they would take measures against Venezuela's issuance of petro coins to circumvent U.S. sanctions, the two chairs expressed opposition. However, the CFTC chairman said that if virtual currencies are used to deceive American consumers, they will not hesitate to take measures.
