the statement or question " how is bitcoin helping poor people?" is question most people often ask, and i usually reply them that there is no free money in bitcoin, the product of bitcoin is what you put in vs what you get in return in a long run. those folks that bought bitcoin when it was less value in the earlier part of 2009 -2010 and or when bitcoin was less than $10 could be seen as the people that benefited more in bitcoin investment but i cant still consider it as help because the profit they made in the long run is worth the time spent in hodling it. because if they didn't have held it till it became valuable, then they would still be poor. 

to summarise the whole issue, bitcoin only help the poor who believed in it, invest in it, HODL on it, and also have patient on it.
