Bought and Lost ~$5,000 Bitcoin gambling in 2017. How should I go about my taxes? Hi personal finance ,

I bought around ~5k of bitcoin on coinbase in various intervals in 2017.  After buying the bitcoin I would immediately send the coin to online sports books and casinos. Sometimes I would win and send it back to my coinbase account (and on the rare occasion send it back to my bank account), but I definitely lost a majority of the bitcoin to those sites


Now that it’s tax time I’m concerned on how and what I should file. I’m trying to make sure I report information that I need to. 

I’ve taken a step back from gambling and am now 90-days gambling free. I hope to continue abstaining from  it in the future.
