A bitter dispute between Paxful's co-founders Artur Schaback and Mohamad (Ray) Youssef in Delaware's courts may have been the real reason behind the Bitcoin marketplace's sudden closure on April 4. 

Schaback and Youssef, who started Paxful in 2015 with a shared passion for Bitcoin (BTC), are now litigating the company's control with several accusations against each other, according to court documents. Misappropriation of company funds, money laundering and evasion of United States sanctions against Russia are among the allegations.
