let's all stop seeing Bitcoin as a source of income because it may cause panic when ever there's a dip or fall in Bitcoin.
A source of income is something that provides you a steady stream and flow of money, either on a weekly, daily or monthly basis, and for something like Bitcoin, you cannot consider it a source of income because you have to invest in it to actually profit from it so Bitcoin is actually more of an investment opportunity or a currency than it is a source of income. If the plan of someone is to regularly make withdrawals from their bitcoin to support their lifestyle and livelihood, those kind of people will find it difficult to really hold or keep any Bitcoin as an investment for the future.
You're absolutely right, if you want to make your bitcoin investment a source of income definitely you will keep tempering your bitcoin wallet, at this point you will find it very difficult to HODL your bitcoin for long term investment, and this is even going to make you not to profit from bitcoin investment, that is why is good to have other source of income so as to enable us leave our bitcoin untouched. Anyone who consider bitcoin investment as his/her source of income that means the person is not Investing in other to get profit rather he's just Investing just like a means of saving money LoL.
