Most of the merchants are simply not accepting bitcoin... But this problem can be solved by exchanging bitcoin to local currency, such as ANXBTC.
This is one of the reasons why people are stopping to use bitcoin or they don't even want to try to use it. Because most of the merchants,stores and other businesses don't want to accept bitcoins for their payments.
But sooner or later they will accept it, trust bitcoin.
They are stopping with Bitcoin if they are realizing that they cant earn more money with it and that they have to wait a long time until the value will be more worth and that would be bad.
But you never know what is going to happen with Bitcoin so it is also hard to make a decision with it and that is risky.
