Since I'm using coins.ph for bills payment and e-loading services, I can always take a quick look on the price of bitcoin everyday. And it has tempted me to buy little by little as the price drops. It help me anyways to invest more on BTC because I sometimes buy it when dropping gradually.
Of course, if you have a home budget there is extra money that you can invest in Bitcoin, do not worry about the risks at all. In this case, you can be much calmer and more courageous than anyone else.
