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.
If ever I'll have the opportunity to have a lot of bitcoin in my hand, I wouldn't hesitate to share it the needy and to those who weren't that fortunate. Sharing is caring so it would not be a big deal for me donating some of my bitcoin to them because I know it will make sense someday and maybe karma would hit me back with plenty of blessings as I keep on sharing the rewards I am getting.
