You know what you must know is that people don't usually know when to invest, how to invest and when not to invest. Usually, investment is when you are financially stable to make it reality but most people nowadays jump into investments without at least having source of income or something that would give them income when they are in need or lacking moment.
It's true that everyone out there loves investments but getting to know the rules of investment is what most people are lacking, that is why many people faces hard time with their investments or ends up pulling off their investments when their time isn't yet to come.
You're absolutely right, this is one of the problem most people are facing, they just jump into the investment without considering some factors, even when they say invest without what you can afford, attleast an investor should got some source where he can consistently lay hands on to service his investment no matter how small it is, starting is good no doubt but sustenance is very much excellent because that the very smart way to go about the investment, when you said rules of investment the first thing that came into my mind is investment concept which I believe that's what every investor should know first before making some conclusions, I think you made very concrete points which are very much vital as far as bitcoin investment is concerned.
