Thanks.  Once they are then back in a wallet then the private key comes into play again?

This  may be  a daft question.  But can I use my Bitcoin private key to get my bitcoin from Coinfloor?

OK thank you for the replies.

I've set up an electrum account.  I have then chosen the option to create a 'new seed' which I have written down on a piece of paper.  I've also set up a password.  Then I guess I go to the 'receive' page and click on the 'New address' tab and I provide this to Coinfloor as an address to send me the Bitcoin to this wallet.  Am I doing this correctly?  I see that that address it's generated is only available for 1 day.  But once there's Bitcoin in it I presume it  becomes permanent?

Well thank you all.  I've managed to retrieve all those forks thanks to the assistance of people on here.  In fact, I wouldn't have been able to retrieve the Bitcoins either if it wasn't for help on this thread.  I've learnt a great deal here.  I'm going to hang onto the Bitcoin.  We'll see how things  go.

Can anyone suggest a good book regarding Bitcoin?  Nothing too complicated.  There's a lot on Amazon.

Incidentally, I've left my Bitcoin on Coinfloor.  Is that a good course of action?

OK thanks.  I am fine with the Bitcoin Diamond Wallet now.  It's the Bitcoin Gold Wallet which is causing me problems downloaded from link from Coinmarketcap.  Can't find anywhere to enter an address or seed or key.

Has anyone used the Bitcoin Diamond BTCD Wallet?  I can't seem to find where it's requires the key or seed.  It's not quite like the Electrum wallet.

I'm relatively new to all of this even though I purchased my bitcoin back in 2013.  I couldn't even remember transferring it to Blockchain.  I was getting confused regarding the address and the key and the seed.  I found the key from a paper wallet I mentioned earlier in the thread and using it, I managed to recover my Bitcoin Cash.  The seed I created didn't.  I also had another 16 word  seed I had written down  years ago.  I tried that and it didn't work  but I think it was linked  to my Blockchain wallet.  I am learning slowly.  When I purchased Bitcoin it was worth around £100.  Who would have thought it  would have reached these heights and until recently, I thought I had  lost mine until I decided to search in an old computed I had lying around and found the account name with Blockchain in my 'favourites'.  My only regret is not having bought more.

Thank you for all your  help.  I've learnt a lot.  I've moved my Bitcoin Cash over to Coinbase now.  Now onto Electrum SV.  Is this the correct link to it's Wallet?  I couldn't find a link  from https://bitcoinsv.com/en

I have just tried it and it didn't work.  I do leave spaces between the seed words don't I?

I did this in Electron Cash using the seed I created in Blockchain and nothing appears.  The Bitcoin Cash still appears in another wallet as an imported address, watching only.  Any suggestions?

OK thanks.  Where in Blockchain will I find the transaction?  

I've found a deposit and withdrawls aread on Confloor and it provides an 'Address' and 'Transaction Hash'.  Does this sound good?

OK thanks for the help.  I have now created a seed phrase as advised by hosseinimr93.  I haven't used it to move my BCH.

A few months ago I had some Bitcoin in my Blockchain.com Wallet and I moved it to Coinfloor without the use of a seed phrase.  I firstly moved it to Electrum and then sent it to Coinfloor.  I'm confused as to how I was able to do this after reading some recent advice on here.  I don't now have any Bitcoin showing in Blockchain but I do on Coinfloor.  Will I be able to sell this?  And the seed phrase I created this evening is only linked to what is currently in my Blockchain.com wallet?  Thanks and sorry for my ignorance.

OK.  I'll have to do that tomorrow as I access my Blockchain from another computer which is elsewhere.  I can't remember seeing any 'private key' in the blockchain wallet?  Just the address. 

OK thanks.  I am trying to send to my Coinfloor wallet.  I've chosen the 'send' tab and inserted the destination address and chosen 'max'.  I can't seem to find a tab or button to make the transaction?  Can anyone help?

It also says, 'imported address, watching only' if that's of any help?

Thanks.  The private keys.

I got confused.  I had download Electron cash as you stated but I hadn't selected "Import Bitcoin Cash addresses or private keys".  I've now done this and they have appeared in the default wallet. I want to leave them there for the time being but I hope to send them to my Coinbase wallet later on. Do you need to save this or just quit or what?  Thank you all for your help.

I have downloaded electrum etc.  I'm having difficulty in importing the bitcoin cash into the wallet from Blockchain.com  Any suggestions....again?  :-)

Actually, have purchased some alt coins through coinbase.  I liked ByBit where you can purchase on margin.  Something similar is what I would ideally like.  I like the flag.

Do you know of an exchange you could suggest to me?  How about spread betting?  Thanks.

Thank you both for your replies?

Is it possible to easily use ByBit in the UK?  I looked at some youtube video which said it was not but I believe you can get around this by using a  VPN.  Anyone using it from the UK and what VPN are you using?  Who or what prevents you from using it in the UK?  Is it the banks refusing to deposit money with it or what?

Also, after purchasing some crypto on ByBit, how do you convert your money back into fiat afterwards?

Thanks for any replies.  I'll return later.
