In 2012 and I could still beat myself for selling it in 2013.
Oh, yes, my situation reminds yours. I started to mine Bitcoins early and later I took a decision to sell them. I do not think that several years ago, people could guess that BTC would grow in price so greatly.
Since I know BTC, at the end of 2017, when the price of BTC is quite high, I can not afford to buy and I also predict that at that time BTC has reached its peak, if we buy it is easy to lose because prices will fall. And as I predicted. At present, BTC is decreasing strongly. It is unlikely to increase the breed by the end of 2017 and early 2018
