Hello!
i need advice,  i have three small  stores  where i sell Phone, TV,PC  and sell cash for bitcoin using a Pos Hardward.
One month ago, Someone wanted to buy my stores and he  asked me to sign a LOI, and after he made a deposit to my account . After one week he asked alot of papers , Bank statement and Hot wallet.

Two weeks ago ,he told me that he discovered that my hot wallet lost 59.788 bitcoin within 1721 transactions  between 2016 to 2020 and the scammer is the Bitcoin ATM manufacturer that sold me the POS terminals.

I contacted the company that sold me the POS , i shared with them the 1721 transactions with TXT iD
They replied and told me that they dont have access to server from 2016 to 2020.

What i should i do? can i sue these criminals for scamming 59 BTC or open an scam accusation againts them?
