Experty is one of them that lost user data.
The Experty example should be enough to frighten anyone.
I really hope the crypto community at large realizes the potential impact they are having by participating in this disturbing trend called KYC. Please think through what crypto's true value is and pit that against providing all your personal info to individuals who you do not know and who cannot possible protect the data 100%. Hopefully the fact that your actively hurting your own investments by doing so dawns on you. Your freedom and future generations freedom may also be at stake. Please wise up people. You may have a real chance at financial freedom here if we can punish all projects who ask for this information.
