Good,
I usually use www.poloniex.com if you want you can register there with the referal 9CHGUKBS.

Once in poloniex, you go to Wallets, search for STORJ and Deposit, and make a transfer from myetherwallet to poloniex.

Now from poloniex you can change the STORJ to USD dollars to be able to withdraw them.

a greeting

Thank you very much, I also had the same doubt Marco, Thank you for helping me to solve it, I registered in polinex, with your referal, I hope it helps, greetings!

What is not clear to me is once we have transferred to polinex where we request that they send us the money in USD.

Thanks and apology the inconvenience.

Can you help me. How do you convert Stroj in Poloniex to USD?

Thank you
