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.
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.
Faith doesn't keep our Bitcoin investment running rather it is our commitment for been consistent in accumulating Bitcoin that does.
If we are just hoping that we will make profits out of Bitcoin without investing a penny on it,it means we're daydreamers . Bitcoin investment requires money to start with and that's why before thinking of investing in Bitcoin,we should have something doing that earns us money even though it's not consistent , it will keeps us ready for the tasks ahead in sustaining our investment while maintaining a healthy Bitcoin portfolio.
So what's is needed is funds and not Faith.
