bitcoin like a fiat currency can be good or bad depends on how it is being used, it can be very good tool if been used to help the needy or the provide the needs of one's family but can be bad if been used to buy drugs and been used to finance those terrorist acts.
ea, it is a currency and can be used for god as other currencies but the problem is that most of the poor people do not have access to bitcoin, so they cannot get bitcoin, I will suggest that for them we have to buy things with our bitcoin and have to give to them and if they need money then we have to convert some of them into fiat and have to give to them.
so the better good will be that he give him access to the internet and teach them to earn money with bitcoin. So he will feed them for lifetime with minute expenditure.
