Old-school Deribit I wrote a post earlier comparing the annualized returns of dual-currency investments on exchanges versus Deribit options. And why people are still willing to stick with CEX for dual-currency investments. Someone commented: "Because they can't use Deribit." True, I had only registered an account before but hadn’t completed KYC yet. (Surprisingly, I found out I registered back in 2021.) So recently, I tried doing KYC, and that’s when I realized it’s not simple. Identity info, document verification, address, source of funds, bills, etc. After submitting everything, the system told me my KYC was unsuccessful. First, they told me not to use a VPN to log into their website (but I wasn’t), and second, they asked me to upload a bank statement because I selected "Saving" as my source of funds. You said your funds come from savings, right? Then print out your savings balance for us to see. Looking at the ¥200 balance in my bank account, I was speechless. My bad—I later discovered there’s a "Virtual Asset Trading" option. Comparing Deribit (and all the derivative sites of Deribit) with any other CEX feels like using Yahoo or Amazon back in 2000. Maybe professional options traders really don’t care about UI, but come on, it’s already 2025—are you seriously not planning to hire a frontend engineer who knows Vibe Coding?
