I'm coming back to this question because I've new experience with earning Bitcoin. You could ask for Bitcoin at Christmas. No matter how funny it sounds at first, but alot of people get money as Xmas present and the money adds up and become a large funding. You could ask for this funding in Bitcoin or ask for money and exchange it to Bitcoin.
That's not "earning" at all, that's called begging. Earning is when you do something and you get paid to do so. For example, working for someone or investing. You worked hard, so you get paid. You invested, and so you have some profit in return.
Personally, I dislike people that ask for money. If you need money, then look for a job. Just because it's Christmas, doesn't mean people shower money and they're willing to give you 1
BTC unless you come from a rich family of course. And to be honest, a lot of people don't get anything from anyone for Christmas, a lot of people don't celebrate Christmas at all.
