QuadrigaCX Exchange investigation still ongoing and the FBI contacted the affected creditors concerning their ongoing researching.
Is not clear and what they said to them but the main reason was to inform the creditors that the late Exchange investigation is still on agenda.
QuadrigaCX Exchange is the one who got his CEO suddenly losing life, taking with him a huge sum of money from creditors, and accordingly with Ernest & Young, almost 20,000 BTC was definitely lost due to the CEO death.
He was the one with the private keys for the offline wallet from the exchange, and with his suddenly death those funds vanished forever.
Recently the creditors asked the authorities to allow them to take an exhumation of the CEO to be sure that he, was actually dead, because mostly investors believe that the CEO was actually alive, and played them, to benefit from the funds.
This new development from FBI give the creditors more warranty to see the case solved but not actually, the return of their hard earned funds... this I assume they lost them forever!
