Twitter became the latest internet platform to ban ads for cryptocurrency offerings, saying these services are often associated with "deception and fraud" Twitter on Monday announced a ban on ads for initial offerings of cryptocurrency or sales of virtual currency tokens, sending the value of bitcoin diving below $8,000.
Twitter followed the lead of Google and Facecook, which earlier this year cracked down on digital currency ads to protect users from being duped.
"We are committed to ensuring the safety of the Twitter community," Twitter said in a statement.
"As such, we have added a new policy for Twitter Ads relating to cryptocurrency."
Under the new policy, the advertisement of ICOs and token sales will be prohibited at the global one-to-many messaging platform.
Some startups have used ICOs, or initial currency offerings, to raise billions of dollars in a highly volatile, unregulated market.
Twitter said,"We know that this type of content is often associated with deception and fraud, both organic and paid, and are proactively implementing a number of signals to prevent these types of accounts from engaging with others in a deceptive manner."
The value of bitcoin dropped eight percent to $7929, after the Twitter ad ban was announced, based on market data from Bloomberg.
The new policy leaves open the door for ads for cryptocurrency exchanges or secure "wallet" services offered by public companies listed on some major exchanges.
Twitter planned to modify its ad policy as the digital currency market evolves, as well as its ability to distinguish dubious marketing messages.
The British government early this year called for global regulation of controversial virtual currency bitcoin, adding that the G20 would address the topic this month.
Bitcoin is independent of governments and banks and uses blockchain technology, where encrypted digital coins are created by supercomputers.
The virtual currency is not regulated by any central bank but is instead overseen by a community of users who try to guard against counterfeiting.
Virtual currency exchanges have seen tremendous volatility, and have sparked concerns they can be used to launder money for criminal networks.
