It may or may not boost your income.
Please note:
Income: money received, especially on a regular basis, for work or through investments.
bitcoin has a volatile price movement that why you can earn profit from this or not through investment. But, you can earn here in this forum if you are joining any signature campaign and bounty campaign. So in this sense, You can earn the bitcoin and can use it to your necessities. However, signature campaign and bounty campaign does not hold you forever even your doing a great job and following there rules since it will only last for a month.
I wont think this is a best choice for a main income. You can have your own business or full time job to support you in your necessities in a secured way.
