Twitter Inc will start banning cryptocurrency advertising from Tuesday, joining Facebook and Google in a clampdown that seeks to avoid giving publicity to potential fraud or large investor losses.
The prohibition will cover advertising of initial coin offerings (ICOs) - crowdfunding used to raise cash by creating new coins - as well as token sales, the San Francisco-based firm told Reuters on Monday.
The new policy, which will be rolled out over the next 30 days, will also ban ads by cryptocurrency exchanges and cryptocurrency wallet services, unless they are public companies listed on certain major stock markets.
For Japan, these will be limited to crypto exchanges regulated by its national financial regulator, Twitter said.
The firm had said this month it was taking measures to prevent crypto-related accounts from “engaging with others in a deceptive manner,” but faced calls to go further after bans from Facebook Inc and Alphabet Inc’s Google.
Facebook has restricted crypto-related adverts, while Google announced a ban that comes into force in June.
The price of bitcoin, already 4 per cent in the red on Monday, fell further after the Twitter announcement. It traded at $7,920 on the Luxembourg-based Bitstamp exchange at 1740 GMT, down more than 6 per cent on the day.
Regulators have stepped up warnings that bitcoin and other virtual currencies are highly speculative and that some could be fraudulent, and that investors should be prepared to lose everything.
But last week the G20 group of rich nations failed to reach a consensus on how to supervise them.
Adverts for virtual coins or ways to trade them have appeared everywhere from London’s transport network to Japanese television as demand for them has soared.
“With the increasing number of ICOs coming to market, it is an impossible task for anyone, much less platforms like Twitter or Facebook, to keep on top of which ICOs and cryptocurrencies are genuine versus frauds,” said Zennon Kapron, director of the financial consultancy Kapronasia.
“Although certainly ICO advertising must have been a significant source of revenue for Twitter, the repercussions of fraudulent activities just weren’t worth the risk.”
Bitcoin has lost more than half its value from a December peak of almost $20,000 as fears of a regulatory clampdown spooked investors. News of the Facebook and Google bans also knocked the price.
Ethereum and Ripple’s XRP, the second- and third-biggest digital currencies by market capitalisation, have tumbled this year too.
While critics call cryptocurrencies a Ponzi scheme that will end in tears for most investors, supporters say the coins are backed by powerful new technology that can replace traditional fiat currencies and upend the existing banking system.
Bitcoin began the week on a down note, declining as much as 8.7 per cent, pushing the biggest cryptocurrency’s decline for March to about 25 per cent.
Twitter Inc. confirmed Monday that it’s banning advertisements for initial coin offerings and token sales on its social-media platform. The decision comes after Facebook Inc. banned cryptocurrency ads in January and Alphabet Inc.’s Google said it would ban such ads starting in June, as part of a broader effort to crack down on deceptive and misleading advertising on their platforms.
After reaching a record high of almost US$20,000 in December, Bitcoin has slumped about 60 per cent as investors reconsider the prospects of the digital currency and regulators around the world increase scrutiny.
The U.S. Securities and Exchange Commission sent a number of subpoenas earlier this month to ICO teams it suspects are breaking securities regulations, and it has warned since July that some of the offerings may be breaking securities regulations. Twitter said on March 7 that it was implementing measures to prevent crypto scams.
