It is correct that we should at least spend our bitcoins not just hold it because it's a way to support merchants and promote bitcoin as well. Not only during black Friday or holidays but anytime we feel like spending it. Though I haven't bought anything because I don't want to spend my bitcoin on not so important things. And recently, I just bought something necessary so I have to save up before spending again.
I honestly didnt buy anything. Because I want to save more coins so that in the future I could use it to buy more and to buy anything that I want. Invest now, save your money and produce more of it so when the right time will come you may now enjoy your investment and savings as well together with your offspring.
