I am looking to purchase my first bitcoin. I have the app BTC Wallet, what is the process for acquiring my first bitcoin. Do I give the seller my e-mail address for my wallet?
You just need opening account on exchangers that supports for your countries
then doing deposit fiat money on there and buy bitcoin after that you can withdrawal to your bitcoin wallet,
if you want buy bitcoin from other users not from markets, you just need give them the wallet bitcoin and don't forget always use escrow for the safety.
