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, all of which have had data breaches resulting in user data being strewn across the internet?
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.
What can I say is most people either doesn't understand what is privacy concern or doesn't care with their privacy. People usually say they're have high privacy concern and would protect their privacy, but they're submit their KYC to an exchange which is kill their own words.
They're only look from the past history where the exchanges have very high popularity and no KYC leaked so far, but the future is different and you can't predict the future with the past history. They thought as long as now there's no problem, why should I care about it? but when the exchange got hacked, they will regret what they've done.
