I know few of us started usage of BTC from Ponzi Scheme before we metamorphosis to Cyrpto-trading. I'm sincerely sorry for your lost. What I can say is that you may see it as a loss now if you sell it off and quit cryto, but if you are a holder and also follow updates and read crypto currency news you can trade your btc for fiat and started recovery bit by bit until you are break-even. Also if you still hold it hopefully by 2020 the price will skye rocket and you become a winner. All the best!
