Bitcoin payout and taxes

Let’s say I win 5,000 online and have the payout sent to me in Bitcoin to my wallet. I then move it to cash app and in a few days it is worth 5,100. When I cash out that 5,100, Do I only need to pay taxes on the 100 in capital gains since there is no record of where that original 5,000 came from? 

Ah, tax evasion and money laundering questions are the most interesting 

There is a record, all gaming sites are required to report large  winnings to IRS, and have to be claimed on taxes

@Cowbeagle

 Furthest from the truth. 

@alldub

 When I won a $4000 parlay last year, fan duel immediately sent e mail stating winnings were reported . Unless things have changed, assumed all books report winnings 

Totally incorrect --- in US, licensed books absolutely, I think anything over $600 in total winnings (may be different per state) 

Offshore don't want, nor have any part in that... 

Problem may begin once you have it in your bitcoin wallet.... u make a $100 on the bitcoin increase, absolutely Uncle Sam will expect their cut, on the $100 and the 5k...

When I did my taxes online this year.... any dealing in bitcoin / crypto was one of the first questions they asked....

Not including any writeoffs you may have for whatever reason, starting with a clean slate on Jan1,as an individual and not a corporation:

you win $5,000 and on the conversion FX or Crypto it turns into $5,100:

Legally 5,000 is treated as ordinary income and

$100 is a short term capital gain.

Yes but you can write off all losses against these gains and you’ll probably have those

more importantly: if you are smart enough to cash out your crypto gains be happy you made them and pay the freaking taxes.. these manias die forever or do you still own AOL and Game Stop at 300
