It's that Bitcoin has been taken over by large corporations and governments...Many stupid people will tell you...
That they have Bitcoin or create derivative products like Futures may affect the price but:
- Bitcoin is still unforgeable
- Bitcoin is still uncensurable
- Bitcoin is still unfishable
It's not that hard to understand, make Bitcoin your bank, create black markets and live your life, you've never had it easier.
Naw man, they are playing our game now. The old rules are out, spread the word. 
I am going to give you an example of a market where a lot of black money is used, such as the sale of second hand cars.
As a seller you are exposed to be given fake money, and if you deposit it in the bank you risk that the tax office will send you a letter even if you have not made a profit with the sale.
Why not just use Bitcoin? Solve the above problems, apply it to anything.
Drug dealers should also start using Bitcoin.
Yo, it is also fungible. I ain't dealin no narcota with that
