The point is to keep a bitcoin separately for donation to the poor. Donating a bitcoin directly will make sense if the receiver is aware of the functioning of bitcoin and Cryptocurrency. A poor and / or needy man can be sometimes an educated man or a knowledgeable man who is struggling to meet his ends. Bitcoin can otherwise be encashed and given to the poor.
It is always better to think big. I would rather create a trust or try to invest in healthcare or education of a poor child. All quick helps will not last long. Educating one child by spending a $25000 or more will reap great benefits to the society in comparison with feeding a whole lot of people once with the same money. Though it is not bad to feed but it is better to invest in a system that more than once continually feeds.
Yes I will donate Bitcoin to the poor and needy the way I feel is best useful for them. One percentage of the income can always be set aside for donation. After all, life is short and it is best to help as much as we can.
I would rather give them food than donating them a bitcoin because they are poor means no cellphone to use, no wifi to use and if they are poor then it means they dont get some knowledge because they didnt go to school. I rather educate them and give some inspiration to live life to the fullest because helping a poor/needy person is one of my goal.
