This KYC is implemented for countering cheating on the 25$ XLM giveaway. but in my opinion I don't mind giving away my passport details or my electricity monthly bills if this is what is required on the rules for claiming giveaways
I also passed kyc and nothing wrong with this I do not see, tembolee this wallet is very well established and I use it for a long time and there were no problems with this wallet I have.
