Go to a
BTC meetup. Those happen in many countries, and declare you have
BTC for sale right away.
Let's say you made some money through faucets, signature campaign, whatever, and you have 5 BTC.
Not sure how much of a newbie you are, but you'll never make 5
BTC through faucets and signature campaigns. You'll have to work to get that much, or buy them at an exchange.
