When I was very new to bitcoin, seeing the price of a single bitcoin and the different earning possibilities thought soon can be rich but only after weeks and months passed understood how hard its to earn much. Now for becoming rich have decided to take it as an additional source, investment and day job a main source.
Yes you are right, it is very hard to earn in bitcoin. You must be dedicated in earning it. It is just like earning the real money. So you must be serious about it, because 1 bitcoin people tend to think that it is only a small amount and easy to earn but in reality it is really hard to earn.
So, you must have different source in able to earn it for real and become rich at all.
