user120130: I don't know if someone can help me but I found out someone has stolen several times some crypto of me, mostly bitcoins. He had access to my computer and my phone to do the Google Authenticator because he is my IT guy.
I know who it is and everything is on police investigation but they can not do much on it at this moment.
So I would like to know if there is a possibility to track my Bitcoin transfers after they have been exchanged to another crypto.
When I look on the blockchain we just see 1 transfer and after this no trace anymore.
We already know he exchanged some Bitcoins to Ethereum, but how can we track or trace this exchange?
Is there a possibility to know which Crypto Wallet Company received my stolen Bitcoins?
Thanks for your help.

There is always a possibility but it is generally beyond the capabilities and resources of a single victim. If you and other identifiable victims have lost the equivalent of millions of dollars then you may be able to get local police engaged. Otherwise you will need to spend large sums of money with blockchain analytics firms and gather evidence that can eventually be built into a legal case that can be used to compel exchanges to divulge confidential customer data. Legal costs may be substantial and involve lawyers in several jurisdictions.
Remember that cryptocurrencies like Bitcoin were designed to make this difficult. Services such as mixers were created to make it even harder. Following money through multiple cryptocurrencies will be harder still.
