The recent Cambridge analytica scandal with Facebook has raised concerns about the protection of user privacy, I think this is an opportunity for Bitcoin and blockchain technology that offers a solution to this issue.
The blockchain technology was created in order for wireless and electronic payments to be convenient compared to sending money through different platforms. Facebook, on the other hand, utilizes a different mechanism under the complex system of the internet and softwares which I believe is irrelevant to the blockchain technology. Though it may provide security and anonymity, social media websites typically have a different application used.
Which I feared all this time against facebook eventually happened also where the personal data of the owners of the account are distributed away. Hopefully, the data is not used for things that can result in losses on the account owner. Things like this I've anticipated by never following a game or various surveys that are in facebook that requires charging some personal data.
The only thing that I fear is the implication of it to the users. If the recent scam on Facebook revolved around the leak on security and privacy, then there is always the possibility of it happening to the blockchain technology in the future. Whatever exists on the internet is bound to be leaked and hacked by some malicious softwares and abusers. That is the reason on why having an electronic wallet is not guaranteed 100% safe, despite having all security measures installed.
