You can use my site:
https://apicoin.io, to easily setup a cold storage wallet. We can also help you broadcast signed transactions. We never hold your funds, or ask for your private key.
Is this as a substitute for using the Bitcoin daemon online or are you just advertising.
It can be substitute for bitcoind, as it is a highly scalable api, robust and extremely secure. The only thing we don't do is hold user funds or request private keys. You will need to sign transactions on your own server or machine, I suggest an offline machine for security. Everything else and more you can do with my site.
