alternative ways of contributing to ones income is what all of us do or aim to do whether we use rakuten, lolli, etcetera, side jobs, work for family friends. start a small business. all of these things add value i would argue . i like to pick up satoshis in free time considering possible appreciation , whats earned here today may be worth more tomorrow. to flat replace an income is an ideal many of us strive for but wind up finding we need multiple avenues to offset cost of living.
