I have a checkbook LLC IRA
My IRA owns the single member LLC
Through the LLC I bought and sold some bitcoins last year

When I went to file the Texas franchise tax report, it is asking
for revenue.

Do I have any revenue? I've only bought and sold bitcoins thru the LLC
If I have revenue, how to I calculate it?

To keep it simple, lets say I have the following
transactions in 2017

Bought BTC worth 5000
Then sold them for 7000

What is my revenue, if any?

Thanks
