So does Blockchain show literally what has just been mined?
blockchain.info shows a lot of stuff, the front page shows the mined blocks and new transaction in the Bitcoin system.
(Guess I will have to explain that next ^^)
I apologise if what I say next sounds stupid but I really am teaching myself from scratch. I'm just investigating wallets because I don't even know much about those - are there different hosts for wallets then? I just downloaded Multibit but your signature has a different wallet provider and there's one on Blockchain too? Do you get a generic wallet file that can be imported into any host? Does it matter which host you use?
I've seen people posting a wallet address - is that their own personal wallet reference to send stuff to? It looks like a long series of letters?
Wow I really am lost down this rabbit hole bare with me!
Ok let's start with some general stuff how Bitcoin works (going to get a bit mind-blowing):
Bitcoin works with a history of all transactions (yes all ever made), this is the blockchain.
You never have any actual Bitcoins on your computer, what you have are Bitcoin addresses and the corresponding private keys to that addresses.
The private keys allow you to spend the Bitcoins on an address. (So keep in mind that everyone who has access to the private key can spend the coins!)
All those wallets are different ways to manage these private keys and bitcoin adresses.
But actually both are just strings of numbers and letters and you can literally store your Bitcoins on a piece of paper (called paper wallet)
For an example check here:
https://www.bitaddress.org(yes you can have as many Bitcoin adresses as you want)
There are local wallets (bitcoin-qt, Electrum, Multibit) which you can download on your PC.
The original bitcoin-qt client downloads the whole blockchain (>12 GB), the other two are light clients that don't need the whole blockchain.
The blockchain.info online-wallet does work quite similar to the local wallets,
Inputs.io is more like a Bitcoin bank, it has some nice features, but also requires you to trust the owner of that website.
All of those are good for daily use, but not secure enough for storing bigger amounts of Bitcoins.
Paper wallets or cold storage are the best way to store them securely.
Cold storage is having your coins on a digital medium that is always offline (laptop/usb stick/sd card..).
You can receive Bitcoins to any address without connecting to the internet.
A professional use of cold storage is the Armory offline client, which also allows spending Bitcoins without internetconnection on a cold storage laptop.
The rabbit hole goes deep, it's hard to know where to start explaining ^^
