Poverty is never an excuse not to invest in Bitcoin as long as you're alive and healthy.
Even though Bitcoin investment has no boundaries since anyone can come in to it within their level of finance, but the truth must be told that being alive and healthy is not enough for anyone to come into Bitcoin investment, there must be a means of satisfying whatever you might consider to be your basic needs and then have a disposable income which is the left over cash after ensuring that whatever you consider to be your basic needs has been taken care of, poverty is different measures and that is why Bitcoin investment is very much open for both the poor and the rich according to their level of discretional income.
