Please elaborate. You clearly feel a more detailed explanation is necessary. Please outline which countries specifically you are referring to, and what the differences in KYC laws are that you feel I missed. Don’t simply complain; provide meaningful and useful information yourself. I am discussing in general terms, as OP is likely from the US or somewhere with similar KYC laws. If you feel a more detailed discussion is needed, now would be a good time for you to bring that discussion into this conversation. This is a topic that you clearly desire more information to be available on, so I would encourage you to provide the elaboration you clearly think is warranted.
I am discussing only in general terms most likely to be applicable to OP. If you want to expand this discussion to a more comprehensive answer, then please do that homework for us. If you desire to move the conversation in that direction, then that is an assignment for you to undertake.
