Steady income can be achieved by many ways but according to me i am quite sure that its not possible with bitcoins right now, These days due to lot changes in rates makes the trading unpredictable.
Indeed! For steady income you need a source that produces steady profits and this s yet not possible with digital currencies. They have unstable natures; the prices are fluctuating all the time. For steady income, we need a day job but for grand profits I am investing into bitcoins.
The best to have a stable income is to find a job and just increase your income with the activities you will be doing here.
Crypto are profitable but there is no guarantee it will last so be safe all the time, don't go big when you are not ready yet.
