Just like you have said we don’t require to get all the knowledge about Bitcoin but just some little details on starting an investment in Bitcoin, But I will disagree with you about having faith for bitcoin investment because it has nothing to do with faith I really don’t think bitcoin got to this level all because of faith, I think you don’t need a stable income to invest in bitcoin but rather what is required is Discretionary funds, For instance you have a stable income and at the end of the week or month after paying your expenses and bills and you don’t have a discretionary income left so how do intend to start an investment. Definitely there are people who are investing in Bitcoin and don’t have a stable source of income but they still invest and accumulate with the little income they have which might not even be stable, but they still stay consistent in there accumulation.
What I think about this is that once you have a source of income you are good to go, because it's through that source you will be making out your discretionary income needed to invest in Bitcoin, but for your investment journey to be smooth you need to have the basic knowledge about Bitcoin and how to go about your accumulation, alone the line you can learn more and have deeper knowledge on all that pertaining to Bitcoin investment.
As for the aspect of faith, it's very funny to think that faith plays a role on how successful you are going to be, because even the bible says that faith without works is dead, so if you don't do whats need to be done, their is no way you will be successful in your investment wether you believe or not.
You are right but I doubt if faith really has something to do with our investment, I believe the most important thing is always doing the right thing, that is applying the principles of Bitcoin investment which will aid one to a successful state. Everything in life has principles and how to go about them and nature made it that way, while going into Bitcoin investment, for a start you don't really need too many knowledge to start because there is no need for it and it is not all source of income that is advise to be used to invest in Bitcoin, any source of income that one barely eat well from should not be use for Bitcoin because there is a high chance of regrettion sooner or later.
