Just been using the KNC wallet and can't send Bitcoins?

Would need more details to try to help you.

No. You cannot prevent anyone from sending you coins. Once the transaction is validated and enters the blockchain it gets more and more resilient with each new confirmation.
The only thing you can do is send them back or spend them. Otherwise the coins will be available balance to spend by the receiver of it.

I think it is just impossible to set up any blockage.

if you use each time new wallet you lessen to have bad senders knows and send you money.

This question seems to indicate that you are having trouble sending Bitcoins. 

Are you asking if you can block others from sending Bitcoins to you, or, are you asking if it is possible for you to be blocked from sending out Bitcoins?

Please be more specific and we may be able to help you.

Remember a week or so ago, when lots of folks were receiving a single satoshi into their wallets? It was the NSA conducting trials on some special hacking algorithms to see if such a thing couldn't be accomplished indirectly. The idea was to send every bitcoin address in the blockchain a single satoshi in such a way that would make record keeping and tracking ponderously enormous. Just a test by the NSA to test their own abilities. After all, what's the significance of a source if it goes everywhere?

There are such things as "watch only" addresses - where you import a Bitcoin address but not the corresponding private key, meaning you can watch it and send coins to it but not spend from it - but sending from your default KNC wallet should work exactly as you would expect.

What happens when you try? Presumably you scan a QR code, enter the amount to send, press "Send", then what?

Off topic and no proof, just wild FUD with no value.

I downloaded the KNC wallet for Android yesterday as they were giving free BTC with it, I got 0.0015. When I try to send it to my main multibit wallet I get an error saying: problem sending coins.

Has anyone else had this problem?

Sorted, you cant send the entire balance.

Feel kinda embarrassed now
