Although it sound interesting but hard to achieve that amount of %30 on regular basis expecialy on DCA strategy. Considering the responsibilities in the family. for example a country like mine, if you continue like this you will put yourself in financial jopady. For me I think %20 will be good to go. but if one can develop and nuture that characteristics, I think it will go a long way if there are other means of lively hood.
You don't have to force yourself to invest in bitcoin if you don't have the funds. If 30% of your wages is too high to invest in bitcoin, go for 20%, and if it becomes difficult to spare such a proportion from your salary in the long term, you can still cut it to a lower price. When you don’t have a means of even saving again after you’ve done some investment in bitcoin, you can leave it for a while until you’re strong enough and financially buoyant to invest in it again. What is more crucial is that you do not spend money that has already been invested, since this would violate the DCA approach and have an impact on your overall savings over time.
