Most people can save some money, except at times when the luck goes against you, in which case you have to draw on saved money. Is that coffee at Waynes really necessary, or that last pint of lager?
The fact that bitcoin is sound money, and currently most probably will rise in value, and the probability of it's value going down is smaller, is in fact good for the small guy, the one who does not have enough to invest.
Its true that we need some cash to do investment but how are you going to invest if you didnt have that sum of money? I mean the real job payment is fit to them and they dont even know how to save their money anymore. How are they going to get their money and how much do they need to save it? I think for their cases it would be easy to save or do some investment
To have something to save or invest, you have to earn and not consume all. The idea is that if you have only a small sum, don't invest, just keep the value in the form of money. Bitcoin comes to mind, it is good money and there is no lower limit.
If you want to invest, you don't have to do a project like a shop on your own. You can take a share in a collective investment effort, a public stock company. With the internet brokers, you can play small, buying single shares with a very low cost. I don't say it is worth the bother, just that you can. There is no excuse for not saving or not investing nowadays. Either you want, or you don't want.
But the turnover from this low sum of money is not good enough, some people need fast money but the cost is low so they can get a big profit from it and can start to do things with that profit. And about share, that is not something you can buy easily because you need to pick which share is good and profitable and some profitable share need a high fund to buy
