Bitcoin Armory, got BTC deposited into my wallet but it is OFFLINE, NEED HELP GETTING IT ONLINE!!!!

as the title said, i got a deposit into my bitcoin armory wallet, and its offline, i think cold storage is the word used. I am looking for help getting it back online as i am not a computer guy in the slightest. its all very very new and scary to me, ive moved it to my D:/ drive for more space, did the little that I could. I would greatly appreciate any help and figured this is the place to do it. Ive found out the company is dissolved and it is maintained by the community so i figured why not come to the biggest community in the world!

If I knew how to make an offline wallet or paper wallet I would move to bitcoin for all my online transactions. Help me become a bitcoin user instead of a fan.

Feel like this is the same issue that a lot of people I talk to have as well. They want to be 100% sure they can protect their own money and confident they did everything right. Its not a lack of trust in bitcoin stability or price but on the process itself creating an offline paper wallet correctly on my end.

An offline Bitcoin Core Wallet's public address appeared online immediately

I installed the Bitcoin Core Wallet on a brand new installation of Ubuntu. The machine had not been online at any point from the installation of Linux onward. Right after installing the core client I checked the wallet's public address on blockchain.info and it was there! How is that possible?

Why would Ethereum users store wallets online, which resulted in the recent hack, instead of Bitcoin's offline wallets?

Sorry if this sounds obvious, but I have not seen this asked and answered.

Should Bitcoin target a "split" node/wallet architecture? i.e. (1) An online full-node in a remote datacenter, with DDoS protection, high bandwidth, and 24/7 availability... and (2) An offline wallet locally (in my home), with just my private keys - used for signing, like with cold storage or SPV.

I remember over a decade ago when some hobbyists still managed to run webservers (for websites) from their homes. (I believe this involved working around DHCP in order to get a "static" IP address.)
Nowadays of course, almost nobody runs a webserver (for websites) from their homes. They spin up a VPS someplace like Amazon EC2, DigitalOcean, etc.
However, there seems to be this massive "phobia" against running Bitcoin full-nodes in datacenters.
But on the other hand, we have already heard many people saying that:
In addition, there is the concept of "SPV" wallets (simplified payment verification), where a user holds their private keys locally but checks the corresponding (public) addresses online (not on their own local machine) to see their balances.
Similarly, cold-storage or an "air-gapped system" (such as the approach used with Armory, or other wallets which implement BIP 32) (both of which require HD - hierarchical deterministic wallets - in order to keep the online wallet and the offline wallet in-sync) are in some sense similar to SPV wallets - in that the private keys are kept on one (permanently offline) machine, while the (public) addresses are kept on another (online) machine (at the user's location in the case of Armory and other "cold storage" or "air gapped" solutions - or on a remote server in the case of SPV).
OK, so summarizing, this is the background:
  • online nodes need 3 things (DDoS protection, high bandwidth, 24/7), so they should preferably be run in datacenters
  • offline nodes are good for privacy (air-gapped / cold storage), and need little or no connectivity, so they should preferably be run in people's homes
I know the following are probably in some sense really old and obvious questions - but I want to ask them here again, because I do not feel certain that the community has gotten a fair chance to fully answer them, due to the notorious distortions in the recent debate about "max blocksize":
(1) Given that webservers are pretty much all in datacenters, shouldn't we also expect (and embrace) the inevitability that Bitcoin full-nodes will also pretty much all be in datacenters?
(2) Given that the only thing I need in order to verify receipt of funds is:
  • my private key
  • some access to an online machine which can verify the corresponding (public) address
...then shouldn't I be indifferent (neutral) as to whether I do this (the online part - just verifying the funds at an address) on a local machine in my home, versus on a remote machine in a datacenter?
Indeed, for security, I don't even want my private keys to be on an online machine anyways - I want to always use a "cold storage" or "air-gapped" approach as provided by Armory (and some other wallets which implement BIP 32), on an offline machine.
So this would seem to suggest a specialization of Bitcoin software, into the following different programs:
(1) online full-node software (for relaying blocks and transactions, and for checking the balances at addresses). This is the software which needs:
  • lots of bandwidth
  • DDoS protection
  • 24/7 availability
The above program should be running online in a remote datacenter.
(2) offline wallet software (for generating private keys, and signing transactions).
The above program should be running locally, in my home - possibly even offline, for greater security.
Note that a fundamental requirement for this architecture is HD - hierarchical deterministic wallets: an easy-to-implement feature (but one which Core/Blockstream has neglected including in their wallet).
This is needed because if the system is "split" between an online part and an offline part, then HD is needed in order generate identical sequences of private keys, public keys, and (public) addresses on both machines.
Summary:
From the point of view of:
  • online throughput (of full nodes)
  • online DDoS protection (of full nodes)
  • online 24/7 availability (of full nodes)
  • offline cold storage (of private keys)
We really want a two-part system, consisting of:
  • an online full-node, which could be in a remote datacenter (and which multiple users could probably share)
  • a (possibly permanently offline) local wallet (which is mine alone).
Since this kind of "split" architecture is actually the one which would best would satisfy all our needs (throughput, DDoS protection, 24/7 availability of the online part - and low resource usage, and total air-gapped / cold-storage security for the offline part) - then why aren't we simply accepting this, and designing our full-node and wallet software as two separate programs, each specialized for their respective tasks and environment?

Offline or online bitcoin wallet is best for me? and general advise on how to get up and running in bc buying

It has taken me months and months to get started in the bitcoin arena due to the huge learning curve.
I am interested in anonymity though not obsessively. Ie I am not a darknet pirate that needs the maximum protection however I would prefer that when and where I buy my bitcoins were not broadcast so easily or linked to my main bank accounts.
At the same time I still want convenience. I was told about offline wallets; with those do I always have to buy bitcoins from people in person or from bitcoin vendor machines?
I don't mind the latter too much, although less convenient than just buying online with your card but wouldn't mind for not linking to my accounts; but I don't like the idea of having to meet strangers to buy them I would prefer not bother if that were the case.
And so can offline wallets only be used with offline bought bitcoins? and also is there any ways to protect anonymity whilst still using online to buy bcs? As I said it doesn't have to be airtight for my purposes just more a peace of mind thing.
So basically I would like to know the range of different options in terms of striking the balance between extra legwork for extra anonymity vs ease of use; ie all the main options to see what would suit my comfort levels in terms of convenience and security.

Bitcoin(wallets) online vs offline

When you download a wallet and purchase bitcoin, does that bitcoin actually reside inside your wallet on your device? Or is the actual value stay online from where you purchase it from? The reason I'm asking is because of what happened with Gox and what is happening with Cryptsy. It just seems leaving your coins with an online vendor is just a huge gamble and not worth the chance of losing them.
