i think that bitcoin would have been more beneficial to the poor during its early days compered to now or today. i not in any saying that the poor can not benefit from bitcoin now, just that if they could have bought it earlier when it was way cheaper, by now they would have become rich. i believe why people keep on emphasizing on the notion that bitcoin is for the rich, is because the rich makes a lot of profit from it than the poor. for example a poor guy may accumulate small stash of bitcoin for a very long time to be able to even invest like $500 or $1000. and it will take a long time to make profit and we all know that the higher the amount invested, the higher the profit return. so the rich can buy 1 or 2 bitcoin within a short time frame and take advantage of the price changes. so i believe this is the aspect people keep emphasizing on rich being advantageous over the poor.
Unlike rich people, poor people do not always have spare funds to invest. More often than not, they live from paycheck to paycheck and are forced to borrow money to pay off previous debts. Currently, the average cost of a single transaction on the Bitcoin network is $1.29 -

But its not the end of everything even if they don't have spare funds to invest. Because they could work with it to gain extra income so that they would have another source of fund to use for their Bitcoin investment.
There are lots of opportunity we could find not only in online but also offline. If they are just hardworking people there's good chance that they can work those things and could have Bitcoin investment. But if they are lazy and just think about they don't have chance to invest now because Bitcoin is expensive for sure this mindset will not bring them any success then they have high chance to get stuck on their current situation.
