the only things I have are the restore phrases ( 12 words) and my address given by COPAY.

Hi dear who read!
Is it possible to import bitcoin balance of a wallet into another wallet of another app by knowing its address & recovery phrases?
I had some btc in my COPAY wallet .Now it is a while that COPAY has problem restoring wallet. And no support.
What am I supposed to do ?
Are my BTCs gone?! Do I had to forget it?
Thank for help.

Hi everybody.
I was not aware of realesing multibit HD at all.
I used multibit classic for several months till yestrday that I decided to referesh my windows (7).
I thought I would be able to import my wallet using the private key as usual.
But now i see that the classic version doesn`t exist longer.
I insalled HD version an created a new wallet.
But what about my  bitcoins in my classic wallet?
are them gone forever? if yes, it is multibit`s authors ` fault.
because they must warn me before eg via e-mail or any other way.
now All thing I have , is a key file belong to my classic version`s wallet.
Thank you for your help.

Thanks a lot

Thanks .
It was so simple?
Embarrassing !

Hi everybody.
I am new in bitcoin and I launched multibit just some hours ago.
I have an issue maybe foolish.
How can I copy my wallet address?!
I highlight my address as usual and then right-click to copy. Nothing !
I want simply to copy it by right click in order to be paste it on another to-be-receive tab, but I can not.
can anybody please help me ?

Thanks you so much dear shorena for your exact and useful answer.
another thing to know.
I found my private key at blockchain.info.
you told that anybody who knows your private key can spend your bitcoin in whole? righ?
but how? in where?
I wanted to test it. my private key at blockchain.info is available in some formats : bitcoin-qt ,hex,etc.
which one of them is in use?for example the multibit ask me to import a " file" from my computer while
all of the mentioned formats of private keys are some letters and number that can be only copied and pasted in a text document
which multibit can not recognize . or can a private key be used to import in only the same service?

Hi everybody.
I am quite new in bitcoin. I have a dozen of questions .All of them may seem so amateur , even foolish.
I now but I must learn anyway , hmm?!!
well by this topic I want to know:
1- if I can have all my balance in both in an online wallet ( blockchain ) and in an offline one ( like multibit or armory) at the same time ?!
I mean I can access my coins by each of them I wish in case one of them is out of reach or dont work correctly by any reason.

another thing I wish to know is :
2- I am member of some mining sites and some other faucets.
They send me some bitcoins regularly into my blockchain wallet.
What if I export my balance into an offline wallet from now? Do I have to change my wallet in my profile
in all those sites? Or will all future receiving coins add to my new offline wallet automatically ?!
I appreciate your answering and consuming your time in advance.
