I got my first Bitcoin just by joining signature campaigns as one of the perks of being a member on this Bitcointalk forum founded by the legendary Satoshi Nakamoto. I also purchased small fractions and even tried mining but unfortunately did not work due to the increasing difficulty and lack of profit in mining.
Of course there are many people on this forum who earned their first bitcoins by working on signature campaigns from Satoshi Nakamoto's bitcointalk forum. I am one of them and my first earning is earning bitcoins from signature promotion, that moment is really happy. When I was a junior member I watched many videos on mining bitcoins but I never got any bitcoins in my wallet. But I got my first bitcoin payment in my life just by doing signature promotion from this forum and still getting it is really happy and appreciated.
For me earning Bitcoin through signature campaigns was more convenient and simple. You just need to qualify to the campaign requirements and dedicate your time and effort creating constructive posts to get paid on a weekly basis.
Originally when I was a younger member of this forum I also thought that maybe earning bitcoins from this forum is very difficult. But later I put a lot of effort and time here due to which gradually confidence came inside me and I thought it would be really easy to earn bitcoins from here. Finally I earned bitcoins by gaining merit in this forum and increasing rank and later by working on signature campaigns, although it was quite difficult in the beginning but later I found it easy. And I am constantly making constructive posts on this forum for qualifying and weekly payments and dedicated to getting bitcoin payments from here.
For now, since I have not met the minimum required merits earned for the last 120 days, I am still able to earn through altcoin bounties. But as soon as I got that required merit I will surely apply to Bitcoin paying campaigns.
If you want to get good qualification to join the campaign in 120 days then you should definitely create constructive posts. If you create constructive and good posts, you will surely get there qualification and get chance to register in good signature campaign later on. Since you have created constructive posts and have qualified, you have been able to work on literacy campaigns.
I encountered and got fractions of Bitcoin before diving myself into Altcoins. This forum really helps me and my family a lot. I learn and earn at the same time which is a perfect combination for me.
Since you got a fraction of the bitcoins before you dived into AlertCoin, you will never be attracted to all other coins. But I dove into Alertcoin before I got a fraction of the bitcoins and faced losses there. As currently most attracted to Bitcoin and invested here, I spend my good days with the amount of money I get from signature campaigns. It's great that you are able to meet the needs of the family by working on this signature campaign and learning more about crypto.
