I bought 0.00000000 BTC when I first learned abot bitcoin -- in nov/2013, when the price was ~1200$. So, even though my investment was fairly modest, and (as you already know) I have been able to double my holdings every day since then, I am still quite disappointed by the loss of almost 70% of the money that I put into this coin.
Time is money and you've invested plenty. I hope you are getting good returns on the time you've invested here.
