i am not sure how much you can get when you decide to mining, you said you have 100k to invest in mining section, then i think you will need high-end hardware to mining because this is the only way to can earn much of bitcoin than other people. but in mining, you need to wait before you can earn much of bitcoin like 3-8 month or maybe less, beside that you should calculate how long you can get ROI.

i think you need to thinking to make investment in other way so you don't have to wait to long to get ROI but its up to you.
