Extremely easy process. I had a larger quantity of GPUs I needed to liquidate and can attest to how worth it this was in my case. The team is very upfront with you about process and about how you could ultimately make more selling the cards yourself. However, the headache and time BitPro saved me well exceeded any loss of revenue. Labels were emailed to me, the cards were received the next day and accepted that same day, and the check came 24 hours later. Not sure why I selected check, as they had easier time electronic options that could get you paid even faster.
Overall, professional, helpful, friendly team and very easy process. Highly recommended.
