I have a question: If the Bitcoin's are high like $6000 and I would like to get my money offline, because I see Bitcoin's go down maybe to $5700 for example, is it possible that I send my money, before go down, to a paper wallet and send it back, if I think maybe it grows up back to $6000 or higher but before that happens, to a normal wallet and would it stay in a paper wallet in the same value before it was high?
The value of your Bitcoin in your offline wallet is still subjected to market forces. It is offline only because no one can touch it but the bearer of the private key. Don't get confused by the offline/online terminology.
