China DID NOT BAN BITCOIN. You are right.
BUT BAIDU STOPPED ACCEPTING BITCOINS. If you can't see that there is an issue here then you are a bigger idiot than all of those that think that bitcoin is banned in china. No offence.
I think that has a lot more to do with specific implementation difficulties Baidu was having, and lack of interest among its particular customer base. These preceded the bank news.
Is this bank stuff an issue? Of course. I just don't think it's as much of an issue as you think.
For a bank to adopt a new technology would mean developing new methods, procedures and IT instruments. These projects can take years to complete properly.
I believe banks will adopt crypto currencies but they need time to start and complete the necessary projects to get there. And they need to adhere to the laws if any exist.
If not laws need to be made first, we all know that can take years too.
As you can see alot of work has to be done, decisions to be made, financial structure reform, this doesn't mean the have permanently stopped bitcoin from succeeding it will just take a few years before they can adopt.
