In order to earn a lot of bitcoins of course you need to work for it, and my piece of advice is do not rely on just one source of income because it will not gave you a lot of bitcoins so join in a signature campaign or bounty campaign because for me bounty rewards, which are tokens are more profitable than signature campaigns although they might get fails in some pther instances. And while on a signature or bounty campaigns you can always join in a Twitter campaign sp that you can earned an additional bitcoins and there are alot more ways but those are the things that I do
