@Prayank Because, I thought that if someone gets access to bitcoin node(rpc server) then he can get private key from address.

@Prayank Yea, that's why I asked this question)
At your discretion which way is best for you?

If you can afford using several devices, you could store private keys in an air gapped cold storage device isolated from the server which exposes Bitcoin RPC. Would that work?

@Mercedes What do you mean about "isolate Bitcoin RPC server" ?
If you mean store private key in remote Bitcoin RPC wallet, I did it. I just want to know other ways to store private key

I mean have private keys in cold storage device, and to not have private keys in the node exposed through RPC. Cold storage is widely written of on the Internet.

@Mercedes I'll think about it, thanks, but I think that cold wallet it better for mobile device not for web wallet, but I can wrong)

@Prayank @Mercedes I've just looked that Bitcoin RPC have `encryptwallet`, and I'll be encrypt wallet password of user and then unlock wallet and get private key, I thinks it will be good.

A large enough Bitcoin stash on hot wallets, even password protected, is vulnerable to zero day vulnerabilities. Cold storage is a lot safer, specially if the safe room can be made free from electronic nano insects and other less futuristic intrusion menaces such as electromagnetic sniffing.

@Mercedes I know that cold wallet it's the best idea for store your keys, but for web wallet/exchange-swap it will be difficult(
