Re: Lost Bitcoin

If ever I lose a certain amount of Bitcoin (large or small), how can I track it down or claim it back? Who should I contact?

Basically the same as if you lose a dollar bill on the street. Whether you get the bitcoin back depends how you lost it and also luck.

It isn't nearly the same, you can still track the address on blockchain an maybe try asking for it by note on small transaction, and if it was mistake or something along that, then it could work.
OFC if it wasn't mixed already Roll Eyes

I'd say it is a bit more difficult than losing a dollar bill.
