but can u tell me how on earth one can earn BTC ?
Never heard of cryptotab. Though congratulations in discovering the forum and making an account. It has not been possible to mine using CPUs for several years now. It is usual for new people to hear about bitcoin and crypto and start clicking all sort of stupid links and install malware infected utilities.
First understand that this is a Jungle. Filled with riches for those who know the right tools to use but treacherous and dangerous for those who don't have a way. There are scammers, spammers everywhere. Earning BTC depends on two things:
1. Your capacity to invest.
2. Your capacity to learn.
While judging the first one, that is, your capacity to invest, you have to ask yourself what is the amount of money you are willing to lose completely and not fret about it.
The second question is the most important. You need to learn about Bitcoin and save yourself from the misinformation and FUD out there. Check out youtube videos by Andreas Antanopoulos about bitcoin and search google for Jameson Lopp's bitcoin resources. I am not posting the link so you can do the work yourself.
Understand the basics of installing a wallet and securing your private key and your mnemonic seed. Learn to keep your PC and browser malware free. There are cases where people lost there money after typing their mnemonic seed which was transmitted to a hacker by keyloggers. Understand that Bitcoin gives you the power to be your own bank. You need to learn the capacity you need for this.
Once you are sure that you know enough, the next part that come is earning. As already mentioned by hugeblack, there is the services section where you can offer your talent in exchange for bitcoin. Then there is signature campaigns on the forum itself. You will need patience and knowledge for this. On the forum, your reputation and knowledge is everything. If your intent is sincere, it shows. There isn't the kind of professionalism and respect that would have existed here a few years back, but still, there are people who are working to keep this place functioning and do notice when promising, young padawans come in.
Learn, interact, know people. Build your network and decide what you can offer to the community. You will soon be well on your way to earning some Satoshis.
