I am a newbie.
As I am trying to figure out the best wallet to use, Copay seems pretty attractive.
I am not sure though:  Can it support cold storage?


I presume "supporting cold storage" means, among other things:

- Sign a transaction on an off-line computer, transfer signature information with USB stick, and broadcast the transaction from an on-line machine.
- Being able to transact with keys important from a paper wallet.
- Create a 'watch wallet' to follow what is happening at the public address of a paper wallet.

Can Copay do the above, and/or support cold storage in other ways ?

I heard that copay is one of the good wallet and use for business  and i think connected to bitpay..
If you can save your own private keys that you can import anytime to other wallet is ok i think you are in safe wallet..
But i recommend to use mycelium wallet because  tested it much easier to use and save bitcoin and you can take note the private keys or scan your private keys. .

You can't do cold storage with Copay that way. What you are describing is how Electrum (http://docs.electrum.org/en/latest/coldstorage.html) supports cold storage using two computers, one always kept offline. Both Copay and Electrum also work with hardware wallets. But when Trezor and Ledger Nano S came along they pretty much replaced using two computers for secure bitcoin storage and transactions. Costs less for a hardware wallet than dedicating a second computer; there are some fans of Armory who still use two computers for cold storage though.
