Like trading with a positive trust person is fine.
But I would suggest you that signature campaigns are the
Best way to earn bitcoins.
Like my campaign is the best among every other.
So I earn a lot. all thanks to my campaign.
But still you can try to enroll is a campaign and earn around 10$ per week or so.
Then buy stuff at cheaper rates and sell at higher.
This is done by many to increase profits.
Earnings from the signature campaign is a good thing but I don't see it as the best thing because it is kind of tip given by the advertising company to the users who put company's advertisement in their signature. It should be a secondary or third source of income IMO. There are many profitable ways of earning money which pays more than signature campaigns.
The earnings from the signature campaign is limited But those people who have good knowledge about bitcoin and do not have any other skills like programming and designing to earn from bitcoin can find signature campaign as a good source to earn some extra money from bitcoin and along with that they can also earn by writing some articles on different websites which provide that opportunity and they also can start their blogs and write for it.
Not everyone can earn through blog and article writing as it requires good writing skills and not many people has such skills. Another easy way to earn bitcoins is by trading Altcoins. It is not difficult to learn altcoin trading and if you invest in good coins , you can get good return on investments.
Exactly. I believe that there are two ways to earn good amount of money, regardless of what form the money is. You either are knowledgeable about something that other people aren't or you're going to do things that other people are not willing to do. Without saying, the two creates a synergy.
If a certain method can easily be learned and most people don't mind doing it, it wouldn't pay that much. An example of this is faucet which essentially is just captcha solving. Everyone can solve captchas. Everyone don't mind solving captchas. So the price for solving captcha is very low.
Another example is when you go to the dentist. The dentist is just pulling the teeth out of your mouth yet you still pay him good amount of money. It's because he's knowledgeable about how to pull a teeth without making the patient suffer from infection.
Optional (not really bitcoin related but you get the point): As an example for the latter, you can earn a relatively good amount of money from cleaning the septic tank. No one wants to clean their own septic tank not because they don't know how to, but because they don't want to. People don't mind paying a good amount of money for this task.
