It is simple like the earlier replies, invest only the amount that you can afford to lose.  If you are somehow tight on budget with your current work, you can always find a side job and the earnings from that side job can be invested in your plan of accumulating Bitcoin.  Another thing is you have to be patient and should establish your selling point.  Bitcoin is already known to us but there are lurking frauds and scams that exploit the Bitcoin industry so better be aware of them.
