I'm a regular person with low level of income and I can't reach bitcoin. Advoating that bitcoin is for whole society, is just wrong here since as a low-income-person I can't buy bitcoins.
don't be sad like that, you still can use free source as mention on here and you only need to find what suit with you. there are many good thread that discuss about how to earn bitcoin by free source and once you found, you need to work hard to earn bitcoin. i am sure that you can do like others people do.
