John (John K.) , you are not answering questions.
Is this the site which is only taking bitcoin side or its objective website and defending all people's rights?
- I'm not really sure what you mean here, but this is a forum where people can voice their opinions.

Any end user can read opensource right? maybe your grandma can read it.
- There will be other people who will read the code and sound the alert if it's shady. There is no such way of identifying backdoors easily in closed source work.


Another problem is , when people buy bitcoins.
Bitcoin price increase more and more , how can a "bitcoin company" can give their money back with highly increasing money?
can you imagine that.
- Please take a look at how bullion/fiat currency exchangers do. They hedge their positions. Also, there's always services like Bitpay to lock in the prices for you.
