In my own insight, we must promote bitcoin to help other people to uplift their way of living. We can also help them to be knowledgeable enough about cryptos and about blockchain. Bitcoin is the easiest way to become rich or millionaire. You have lot of choices as bitcoiner, first just invest your money or join campaign to earn money or gain more profit
One cannot become a millionaire just by joining a campaign here. One should keep the goals realistic. However, they are good opportunity for jobless people or students to make some cash by posting here in their free time.
One advice for all such people who wish to participate in these campaigns is that do not rely completely on these for all your expenses. There are chances that these campaigns may get discontinued in future and then you will be left in lot of trouble.
