 ManOnTheMoon,

exactly. No signature campaign will make participant rich, BUT it sure as hell beats saving account in a bank and it costs you nothing. Senior members and above can make their first bitcoin within a year at current rates. Thats nearly thousand dollars.

No its Not True that Signature Campaigns are the Only Way to Earn Bitcoins Because there are Many Other Ways you can Use to Earn Bitcoins Online that are as Follows:-
1) You can Try Out Trading If you have Knowledge about Trading and If you want to Take Risks...
2) You can Offer Some Type Of Services in Exchange For Bitcoins in this Forum....
3) You can be a Affiliate of a Bitcoin Program that Suits you and earn real Commissions for Every Sale Made By your Affiliate Link....

On this board, it's the easiest way to earn bitcoins by joining a signature campaign.
But in general every job could be payed with bitcoins.
The problem is, that for most jobs you need certain skills.
And when it comes to online jobs, you often face a lot of competition as well.
That makes the signature campaigns for many people to their most important source of bitcoins.

There is really a lot of source of earning bitcoin. However, I stopped doing faucets and surveys since it is really a matter of waste of time. The electric bill you used in working on thag is actually mor ecpensive than you earn from that. Therefore, it's better to trade and joining signature campaign and investing altcoin to get more bitcoin.

Put in trading or... Finding a safe investment to start earning passive income with lower risk as possible. Trading only if you are really good on it or you will lose all your pennies earned with Signature Campaigns.
