I believe that bitcoin has many problems as well as benefits. For example, when the price rises, you can see people selling their bitcoins to gain profits. Therefore, the transaction fees also rise, not to mention that you can wait 2 weeks or one to get a confirmed transactions.
It is quite troublesome for me to pay high fees when I do not need much money. Another problem is its stability. As a matter of fact, bitcoin has never been stable. It always increases and decreases and you cannot predict its next movement. It is playing monopoly with us.
The big problem about bitcoin is due to PEOPLE are not being contented all the time, when the price had just reduce to 1% a lot of people already screaming and asking what is the reason, then reduced by 10% they are crying and more than 10% they are so sick and mad as if this is the end of the world without even analyzing first what is happening.
There is no problem in bitcoin, it is just US who are making trouble from it.
