Facebook has taken a step against crypto ads and advertising calling on people to participate in ICO's over its network.
Facebook says the relatively high number of scam ads has forced it to make this choice.
Meanwhile,the crypto market dipped further on tuesday after US regulators subpoenaed popular exchanges Bitfirex and Tether.
Also,an ICO backed by former heavyweight champion Evander Holyfield was shut down after authorities claimed it's coin offering 'Arise Coin' was fraudulent.
