Op I think your calculation is wrong because if you want to be investing $100 in every week and remember in a month we have 4 weeks that is $400 a month and we have 12 months in a year that means 12 times 5 we give you 60 and then $400 times 60 will give you $24,000 so how can you are having $26,000?. That is by the way investing $100 every week is not a bad idea but if I may ask is that how big your Income is that you will be investing $100 every week. Bitcoin investment is not a competition so we should always ensure to invest moderately or based on our capacity though as a newbie you ought to take your investment serious so as to build a great portfolio but that doesn't mean you should use one third of your income to invest because one day it will backfire.
