Hi again 

Right due to my paranoia I didn't feel I was safe with Bitcoin core so after downloading the offline bitaddress.org page from Git-hub Rep I dumped it into an USB key and turned my old computer on in the garage (no WiFi card or network at all) from there I created a paper wallet that I printed.
Now my problem after that was how do I check my balance and how do I use it to pay into it without having to take it out or carry it with me?
I created a blockchain wallet and from there I was allowed to add a "watch only" address, now I will never use my paper private key on line till the day I want to cash out,  hopefully in a few years, so my main question is how safe is my money? Can I keep paying into my paper wallet as much as I want/can? Have I taken the right steps or did I make any mistake It might cost me later?

Thanks in advance for your replies!!
   

Tackling how to work with exchanges is my next step if there's no major security breaches in what I've done.
price seems to be falling

 OK just bought my first BTC investment to test the waters!

Now I have a question I'm in the UK and I've bought from Bittylicious, tho it's very easy and fast to use it's quite a lot of money over price market paid a good £20 quid over . Now is that the usual fee or are there cheaper ways to trade my fiat for BTC in the UK I feel I'm paying a Premium for the service and I admit it's a good service so far.
Now another question is what is the easiest safest way to cash out back to fiat? Im planning on investing on 4 or 5 BTC then hodl for a few years or so but if in a emergency I need to cash out what's the easiest way ATM and will I have to pay a PREMIUM again?

Thank you for your help .

Hello
Pardon my spelling as English is not my main language so allot of technical stuff about  BTC evades me !
I'm new to BTC only started reading and investigating on it for a week or so. I've got a wallet that's still syncing after 4 days is that normal?
Also I've encrypted it and backed it up onto 3 different usb keys even tho I think it's a bit overkill and I don't even have a BTC yet. I also bought sum Darkcoins mostly for testing purposes and they  were cheap and their wallet was much faster at syncing.
MY question is now that I backed up the wallet.dat of both those wallets lets imagine I wanted to transfer it to another computer how would I do that?
There's not option to restore backed up wallet.dat in any of the  clients I have so do I just copy paste it from my usb keys after installing a fresh client on the new computer? also I've renamed the wallet.dat on the  usb's do I have to rename them back to wallet.dat?
Im sorry if these sound like very basic questions and I know and see that many of your are very technical savy but im just an average joe and if BTC has to grow it needs more average Joe's to join and support the  ideal and the  currency I just find the whole system very complicated atm .
Thanks for your replies all help is appreciated.
