It's a repository of known Bitcoin attacks. It's a bit scary though as criminals are going on great lengths now to even attack someone on their home, business and stole your cryptos. And that is why it is very important that you don't flaunt yourself outside promoting Bitcoin. Because once you are spotted, criminals will follow you beat you to death just to get your private keys. So just be careful and stay on the quiet side.
I make a mistake once of wearing a BTC logo once or twice, and then I realised that I'm putting risk on my life wherever I go. So yes, then flaunt when you go out, and always be attentive and get away as far as you can when you smell that something is not right on that environment.
