50% is allocated for investment and 50% is used to meet basic needs. I think that is enough reason but in our country bitcoin is not a payment method, it is still an alternative investment asset so here 100% is only in the form of fiat salary. Luckily the signature campaign salary is in satoshi and that is considered enough for me, at least as long as it lasts then it can be an investment and the fiat salary is used to meet living needs.
