If anyone can earn 1 BTC without any skills and without any investment, i am sure He/she won't teach the way!
There's no such that you can earn 1 bitcoin without any skills and without investments. This is the impossible thing though I'm not believing there's always a possibility but who on Earth will have this laziness and have a blessing of 1 bitcoin? Oh yes maybe it's possible by someone who has a golden heart and will just give it to him for free.
Without skills and investment you won't be able to get that large sum. Because no one gives something for free.
1 BTC is above 4000 dollars. Which is much higher than the average monthly wage worldwide.
The only way could be gambling and the chance will be closer to none.
We know it right, it's just crazy that people want to get what they are expecting without doing a definite return of effort for it. Imagine, how can you earn 1-2 bitcoin for only working a couple of hours a day and remember without an investment, do you really think that there is something that you can earn from that? It's possible but with an investment.
