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.
Well, you can use localbitcoins to buy any amount of bitcoins within your locality and some sellers offer quite low levels in terms of the amount of bitcoins eligible to be sold and so it can fit all levels of income earners without discrimination.
Of course it really fits on all level and it cannot be distinguished if it's a rich or poor type of earners. For me if you're with bitcoin you can be considered as secret type of a kind of rich person. In short words you are not considered a poor person if you do have the skills of bitcoin digital currency trading and other type of income generating microjobs online.
