I am having a hell of a time trying to purchase BCH directly for USD.

I have tried Etoro, Changelly, Bittrex, and a bunch of other exchanges and have the hardest time just purchasing BCH directly for USD. I am hoping to avoid purchasing another altcoin to trade for BCH to avoid the small % fees. I am running into issues because I am in the US.

Is there an exchange I can get BCH? I want to purchase it and send to my wallet. 

Feel like I am being dumb, but am running into issues left and right every time.

Thanks

Agreed, but want to get an S7 and get the hang of things prior to getting the S9. Also, still trying to figure out how I can check to ensure the Antminer is doing what I anticipate it to? Meeting the Th/s spec'd, power consumption, etc..

I am new to the mining, I have ordered the S9 from Bitmain, but am now waiting for 2 months to get it.

In the meantime, I am trying to purchase an S7. Are there suggestions of a where I could get one? Then how can I ensure that a used Antminer will meet the advertised specs the seller is posting?

Thanks.
