In previous years, Bitcoin was known to be involved in many fraudulent activities such as Silk Road, which has been an illegal Darknet market for drugs and weapons. Bitcoin was a big strategy by criminals but luckily, Bitcoin has become more mainstream and criminals were caught. Today, Bitcoin is known for being a reliable digital transactions asset but still some Bitcoin is involved in criminal activities.
Reliable Blockchain companies such as Chainalysis have helped to discover more crimes and make Bitcoin more reliable.

Even if goods sold by criminals are cheaper, don’t buy such goods! Often, criminals have also sold some drugs or weapons previously and such Bitcoin will be from criminals.
Possibly, you’ll also get hacked if someone will place a malicious file in a mail attachement. Be very careful! Better safe than sorry!

It is up to us to improve Bitcoin and get rid from fraudulent and illegal activities involving Bitcoin. We should not support fraudulent and illegal activities, we should not protect criminals or scammers. Bitcoin is very useful but if some criminals will use Bitcoin to purchase a weapon, where possibly people are murdered from, Bitcoin will take damage and we should not support it.
Bitcoin has improved impressively since Silk Road was busted and Bitcoin growing will help Bitcoin to get independent from criminals and scammers.

Beginners should pay attention to avoid falling for criminals and scammers. Criminals and scammers are very deceitful.
