You can follow an ico like a signature campaign and it does not need any capital

Joining signature campaigns are the best way to earn here without investment.
You just need to rank up to at least a junior member for you to able to qualify in campaigns. In here you can start earning and as your rank gets higher the stakes also will getting higher. And if you have funds you can try also trading, but you should learn first the basics. There are other ways to earn but better to start with these.

hi! Im also new here. In my first few days in this forum i read and post and when i reached Jr.Member rank i joined a signature campaign its the easiest way to earn bitcoin without investment.

There are plenty of methods apart from the signature campaigns to earn Bitcoins without any initial investment. But everything will depend upon your skills. A normal data mining job can earn you $2 to $4 per hour, depending on your efficiency. If your English is good, then you can earn $5+ per hour in content creation jobs. If you know coding/programming, then you can earn many times that amount. Later, you can convert this amount to BTC.

I agree that there are many things to do in order to earn online and when you can earn fiat money, you can easily convert it to bitcoin. You can also arrange with your employer to pay you with bitcoin instead of fiat money.

Airdrops can possibly give you profits if you will hold those tokens or coins for a long time, they are distributed because the team or the developer wants to share it or to make some noise about the token so it can attract some attention for the investor and if that coin will be putted in the market then it will be easier for the people to notice it because of the hype that is created in the airdrop.

I think it will not be easy to get bitcoin without investment.
Baisically there are only the campaigns that can deliver bitcoins without putting money in it.
You will not become rich from them, but it's a good start.
Baisically earning bitcoins is like every other way of earning money.
You need skills somebody needs that is worth paying for.

You can start many things. Ranging from creating blogs and active in this forum

1. You can create a blog with good quality and original article writing. With a good blog, you can get lots of visitors. When your blog visitors have a lot, you can put an ad that will pay you with bitcoin.

2. Active in this forum. Create an informative and constructive post. Then make sure your bitcointalk account is already in rank more than Jr. Member to follow bounty campaign. Follow all the rules and you will get a free coin after the campaign ends.

I hope this helps!  

That is a waste of time to put your time and effort in that site because that is only a faucet site with a twist but in overall, it is not worth it to try because it only gives a few hundreds of satoshi that is not even worth for at least a dollar in a few hours of working so it is completely useless site for the people to earn bitcoin without investment.
