People actually think Bitcoin investment is a must and that's where some people do get it wrong because without proper planning, your supposed investment is just a mirage because you might end up using the funds to meet other needs when you don't have the manpower to meet up with investment and your daily life expenses. Many people no doubt today have all end up scattering their investment because of the lack of plan so before going into investment proper planning needs to be done.
Of course, before investing in Bitcoin, everyone should invest according to a proper plan. Many people are too eager to invest in Bitcoin and even start investing without a proper plan. We all need to invest bitcoins in such a way that if we need the money we don't have to withdraw money from the investment and pay for it. If someone takes money out of his investment while investing and uses it for his needs I think that investment has no value.
So if you want to invest, invest with the money that you have left without your family expenses so that you don't have to spend that invested money.
