You get rewarded by making smart ideas, not necessarily by working the hardest. Holding BTC or literally any asset to make money isn't really anything new. Even way back before when BTC didn't exist yet, people held good stocks and made money by "doing nothing"(though the research required time and effort) as well.
Like those users who are in the signature campaign over some years to make a huge amount of money and, it can help them to fulfill their plan to become a great person in the future if they can continue working to add to the ones they have received as a payment in the signature campaign and hodl it for long to receive a good reward that will eliminate Poverty and to open the eyes of the person to see the power of BTC.
Now that people know how to research what will happen in the future like the way people discovered that BTC will be the king among other cryptocurrencies and it came to pass.
I know a lot of people and me included, that end up saving these signature income, some spend it because they really need it but it is not my job, not my work, and it's just added stuff. Imagine working from 2020 to 2024 and collecting about 50 dollars a week on average, that would mean that you would be saving so much money, over 8 thousand dollars just invested, and then some more later on as well.
I think that would make someone richer just by proxy, think about price of bitcoin going higher during that period as well, that would make things a lot better too. So, you would get rich just from this, and nothing more. You wouldn't even need to invest into bitcoin, you just do not take the cash out from the signature earnings.
