The dark web is the World Wide Web content that exists on darknets, overlay networks which use the Internet but require specific software, configurations or authorization to access. The dark web forms a small part of the deep web, the part of the Web not indexed by search engines, although sometimes the term "deep web" is mistakenly used to refer specifically to the dark web.
Every affair in the dark web will use Bitcoin as a method of payment. In the dark web there are various illegal businesses such as the sale of illegal firearms, drug trafficking, assassins and hackers.
What are your thoughts on this Bitcoin abuse?
Well, according to the articles about dark web that I've read on internet, bitcoin is used as a mode of payment for illegal transactions. We can't argue on that one because bitcoin is a cryptocurrency and people who transact in dark web will have no hussle in buying the things they are looking for. However, my point is that as long as you use bitcoin in good ways (buying stuffs, paying bills, etc), there's nothing to worry about.
