I’m only comfortable submitting KYC on huge exchange since some mediocre exchange already have a reputation on leaking KYC info to sell in the deepweb market.
Huge exchanges like Coinbase, which admitted to selling customer data to third parties? Or like Binance, which have been hacked for KYC data which then appear across various darknet markets? Or maybe other huge platforms like OpenSea, Robinhood, Coinmarketcap, or BlockFi?
It doesn't matter how big, how well known, how long established, or how reputable any platform is. Every single time you complete KYC you are taking a significant risk. The
only safe KYC is no KYC at all.
