I am new to bitcoin. I want to buy goods online with bitcoin. I am with CoinCorner and Electrum. My GBP wallet contains £70 and my BTC contains 0.0010969 bitcoin which is £30. How do I transfer money from the GBP wallet to the BTC wallet so I can use it?
If by "transfer" you mean "convert GBP to BTC", then you go to the "Buy & Sell" page.
