Getting started is important and just figuring out the extent to which you have a discretionary income so that investment into bitcoin and building up back up funds (including emergency funds) is not beyond such discretionary income. If such investor is open to learn he can start out with very basics, such as merely starting out with investing $10 per week or $100 per week as he is learning.
I agree with you JJG getting started is very important and To summary everything you just said here JJG.
1, start small and be consistent ( e.g $10 or $100 per week)
2, Invest within your means.
3, and continuously learn and adopt to the system.
