It is unfortunate that someone that does not have a strong source of income may not be able to invest in Bitcoin. Bitcoin investment is known to be make those who have the money more richer than someone who is saving to invest in Bitcoin. Is like trying to fetch water from a well using a cup tying a rope to it to get water to fill a drum. This process is going to take a longer time or even days for such to be achieved compared to someone that has a big bucket to fetch water from the same well.
I have concluded that those who have the capital have upper hand to make more money from Bitcoin than those that would have to save money to a particular extend before they can invest in Bitcoin. The system is built for the rich not the poor masses.
investing in bitcoin is not limited to rich only anybody can invest in bitcoin provided the person has a source of income, discouraging people not to invest in bitcoin, because they don't have strong source of income is very bad, but rather encourage them to start investing with little amount money they can afford to invest consistently using the DCA method either weekly or monthly, because if they start accumulating bitcoin now with little they can afford and hold for long term 5 to 10 or more they will end accumulating a good portion of bitcoin.
Its undeniable that rich people have the advantage when it comes on investment. Since they are capable to do lot of things including acquiring lots of volume or other things they desired.
But low income people should not get discourage about it and better they should not compare their selves on rich people accumulation, since what they can do is to focus only on what they can afford and do since somehow all of us can buy small fraction of Bitcoin and that's good start already for anyone to start their long term investment. What we need in these case is consistency towards their accumulation and keep learning everyday since this is helpful for them to strengthen up their belief to continue their investment for long term purposes. People should not get discourage if they can buy a whole Bitcoin since they can use any amount they want especially if they really want to invest on Bitcoin.
