How are you going to even buy bitcoin when you don’t have a source of income, where will the money which you will be using to buy the bitcoin come from? I don’t even think that’s possible, and Incase maybe you are gifted a money, and you decide to invest it in bitcoin, if you are in need of money, you are still going to sell back the bitcoin, so it’s just better you don’t even invest the money at all.
If you are planning to invest in bitcoin, then make sure you have a source of income, you have a emergency funds, so that whenever their is any problem, then you will be using the emergency funds to take care of it, you won’t be touching your bitcoin investment, but if you don’t have any emergency funds, whenever their is problem, you will end up selling back your bitcoin, which might even be at loss.
Truly anyone that don't have a source of income doesn't have a business investing in Bitcoin because for the investment to be sustained and not tempered with, having a source is very much fundamental to that, their is no two ways about it.
Such person just need to look for a job first, so that he can take care of his or her basic needs, before thinking of investing in Bitcoin.
Because if you force yourself to invest in bitcoin like using borrowed money, I think that is a bad idea. So my advice is to hone your skills first, then after that apply for a job and if accepted then you can think about investing in bitcoin after all your needs are met.
