Trying to trace someone

[clarcombe]

Hello,

A while back, I invested some funds with a trader and I lost contact with him (long story). I know this is a long shot but I still have the Bitcoin address where I sent the funds originally. Is there anyway that through this I can contact the person (assuming the address is still valid) ?

Thanks

Can you check the address on blockchain.com to see if he's still receiving or sending money? A bitcoin address does not expire but this could give you an idea on whether you can expect a response or not.

If the address is still making transactions and assuming his address does not belong to an exchange, the only way I could think of is to try and send him a message using OP_return (give the subject more reading) and check this

This obviously doesn't guarantee he would even notice it but.. Aside from this, can't really think of any other way to contact the individual with nothing but a bitcoin address.

If the individual whom you're trying to contact scammed you... Then this is another story. You're better off reaching out to law enforcement.

If the money lost is big enough, you can get lawyers and professionals to do some chain analysis and hope that the scammer deposited funds onto a KYC'd centralized exchange.

Other than that, probably just let this go and make it an expensive lesson. You're probably better off spending your time making the money back.

I wouldn't call this an investment, it's more about gambling because you give someone money in the hope that they will trade successfully. At the same time, he is obviously an unknown person to you (otherwise you would know how to contact him).
As suggested earlier, check if his address has been used recently, if not, chances are small that you will find another connection with him.
Have you checked the search engine results for that address? Maybe on another forum, social media or similar...

You gave an anonymous person money and now you cannot reach them? Am I understanding this correctly? Why would you give a trader your money if you do not have their contact details?

Sounds more like you got scammed, if you ask me.

But as someone above already mentioned, if that address is connected to a KYC crypto exchange, then you might have a chance to find out who he/she is.

Even if you do what @OmegaStarScream mentioned (OP_return message) the possibility that this trader to notice that message is very slim. Idk the reason of you lossing your contact of him/her either lost/broken device, or that trader run from you but i will consider it already a loss, an expensive experience knowing you tell it as an "investment".

What do you want to do, call his bitcoin address with a phone or send pigeon to find him maybe?  
Short answer for untold long story is NO, but you can always send him more coins on the same address with your contact details, like Satoshi did with Genesis block.
