I want to write an article about this and I've been asking around.
So far, I've found:
* Fraud and scammers
* Government taking over
* Scalability and governance
How about you guys?
Governments taking over! I have been having this fear because of the way things are going. If we look at the mode of regulations that governments are bring on the table we would find out that majority want to take over bitcoin and others cryptocurrency. The beauty of the cryptocurrency is becouse it is decentralized therefore if this is taking out of the place it means governments has taken over.
