Losing crypto and nfts is not the end, there have been many ways used in the past to keep track of these transactions. Glad he's able to handle this because I was also in a similar situation. Few months ago I lost 58 eth on metamask. On pc extension there was no transaction but there was one on the mobile app. Guess my phone was hacked. While searching for a solution, I found a Blockchain Expert's ad who offered to help me get back everything I lost and I'm glad I worked with him as he was very fast and reliable.
