I signed an agreement to loan silver for a rate of interest and able to have my investment returned after one year. Was clearly a scam and I lost my silver. I was told i could file a casualty and theft on Sch A, but looks like its subject to a 10% AGI deduction. i also was told that if related to a ponzi sceme and i filed a timley tax return that could waive the 10% AGi ded. Any thoughts.
