I have used BC for several years. Most places online or brick and mortar that accept BC you don't have to worry about. The biggest place for scammers is at some of the Dark Web Marketplaces (Agora, Oxygen, Therealdeal, Marketplaces):
DARK WEB MARKETPLACES
You can't just click and go to a dark/deep web site. You have to download a special browser (like TOR Browser), and all the websites end in .onion instead of .com. The dark web was originally designed by the US Navy Dept for spies to communicate. That's the "O" in TOR Browser (The Onion Router Browser).
