For me its not safe, but you cant do so much, also nowadays the goverment data sometimes its hacked so...... we dont know if already ou documents are in the web.
Plus i think with the IA thing and some advanced computer things, the bad guys can made fake profiles without ussing so much real persons.
since the government had been attacking casinos and exchanges for verification of their customers, there is need for us to limit the way we give our data to casinos for us to make us le of there gambling platform to bet. We need to try and reduce our urge to bet on KYC casinos because this may cost us our identities been exposed to the government and third parties.
The thing is not to give out our data but how secure the few casinos we trust with our data and how their handle it and the others who are new and unpopular are the most risky since their just start ups and may not have the right security measures to protect and secure the data supplied by their customers and this is what we must understand and guide ourselves against., I am not in support in exposing our personal data all in the name of KYC and also I don't know how to check whether or not the data supplied have been leaked but ultimately centralized platforms must comply with regulatory demands and if you must use them then be ready to give out your documents for verifications.
