I assume scammer has withdrawn your money. It's very different from a centralized exchange site when it pushes its users to register and comply with the regulations like doin KYC verification. Im sorry for your loss but the chance for you to recover your funds is so damn small.
You're absolutely right. If the scammer sends the stolen money to the CEX platforms, he will definitely fall into the trap. By contacting the support of one of these centralized exchanges and providing the required information and documents and the police report, they will freeze the stolen funds and then begin the necessary investigations to return them to the victim; unlike eXch, their policies and services are different they don't follow and track customers and operate outside the oversight and pressures of AML and KYC, so they may not be able to freeze transactions.
Perhaps reaching out to reputable investigators like
@ZachXBT could help unless the scammer has actually benefited from these funds and succeeded in covering up the tracks of his thefts.
It's sad that the OP lost this huge amount of his life savings. Indeed, negligence in securing his assets and wallet was the biggest factor in his loss, so we cannot blame TrustWallet or any other wallets for this.
