Bitcoin declined almost 10% after Google announced that it is updating its financial services policy to ban cryptocurrency advertisements.

The price of bitcoin fell as low as $8,219.73 on Tuesday, according to data from CoinDesk.

In a blog post, the search engine giant said the changes will start in June. Its restriction of financial product advertisements included Contracts for Difference, rolling spot forex, and financial spread betting.

Additionally, Google is prohibiting binary options and similar products, cryptocurrencies and related content. The ban included ads about initial coin offerings (ICOs), cryptocurrency exchanges, wallets, and trading advice.

Googles decision comes as it releases its annual trust and safety ads report. It also follows the step of Facebook, which started prohibiting advertisements about bitcoin, other cryptocurrencies, and ICOs in January.

In an interview with CNBC, Scott Spencer, director of sustainable ads at Google, said, "We don't have a crystal ball to know where the future is going to go with cryptocurrencies.”

He added that they observed that cryptocurrencies have caused potential or enough harm to consumers.  Spencer said, “It’s an area that we want to approach with extreme caution.”

Cryptocurrency market under regulatory scrutiny

Currently, the cryptocurrency market is fragmented, largely unregulated, and wildly volatile.” Investors in the market should be ready to “stomach complete losses,” said BlackRock’s Richard Turnbill in his report last month.

Aside from Turnbill, many other market experts warned about investing in bitcoin and other digital currencies. Billionaire investor Paul Singer called cryptocurrencies as “one of the most brilliant scams in history.”

In fact, cybercriminals have been increasingly targeting bitcoin and other cryptocurrencies through hacking, ransomware, and scams. Over the past several months, the cryptocurrency market has been facing regulatory crackdown.

In the United States, the Securities and Exchange Commission (SEC) recently launched an investigation into the cryptocurrency market. The regulator’s inquiry is focused on ICOs. Technology companies and advisors involved in the digital currency market received subpoenas from the regulator.
