Of course, data confidentiality should come first for any company. But what do we see in reality? Mobile operators sell databases, sometimes it seems that even banks spread information about the contact information of their users. If Facebook adapts cryptocurrency payments, it will only help its rating. There previously were much info that Facebook confidentiality = zero, everyone can buy user's password, what r we gonna see if they launch crypto payment?
Confidentiality ,Privacy or what we call it. for me it doesnt matter anymore. Since we are all in cryptocurrency industry, we just easily give our data to the KYC! that was a very good example that our Privacy or Confidentiality was already gone in our time. remember we are using Internet no matter what we do our information are in danger to leaked and use by others. Thats why for me Facebook venturing into cryptocurrency space is just and ordinary thing and nothing has change. our Privacy are already gone thats the fact.
