Is that an absolute certainty that the funds cannot be retraced ?
Obviously the funds that were sent to Kexbui cannot be reclaimed ....but... if the person was asked to invest in previous exchanges (and made a profit) previously , is there not a way to trace these transactions ?
Several times they wee advised to deposit into Kraken and they did so ..they were to able to access the funds and send them back to their bank account. This was obviously part of the same scam so is it possible that there links to the perpetrators ?
I do not know too much about crypto and it all seems very complex but ..is it possible to find a link .....or completely impossible ?
The complexity all depends on how the perps hid their traces. For instance, there's a good chance perps were using verified exchange accounts from buy and sell market.
You also have to pray your local law enforcement would be cooperative on day to day cases such as this. I've seen cases in where the victim tries to contact the exchange in order to freeze any remaining funds from the perpetrators' account but eventually flopped because they couldn't get ahold of their local authorities.
Nevertheless, try to still file a report esp if your cybercrimes unit is competitive. If they end up being a part of a large crime ring, it's likely law enforcement could spend a good amount of resources on them. I've seen cases of US busting crime rings of such scam scheme fairly recently as well.
