I was one of the original miners, and also put all my money and coins I accumulated into Blackcoin. I also bought low and sold high a bunch when were in the 500 satoshi area which brought me into the top 100. Then we had the pump to 4500, and I missed it, and it was back at 1500. I was devastated at missing my big payoff, and in depression I sold my Blackcoins. For a whole week I had them invested in other coins as I watched Blackcoin not only climb back up, but pass the point that I thought I had missed, and as the days ticked by my BTC went down, and down, and down. Finally today at 6000 satoshi I bought back in and gained less than 10% of my original Blackcoins. I am glad that I got back in because now it is almost 9000. I learned a lot from this experience, to go with my intuition. I shouldn't have let the market shake my confidence in Blackcoin. This experience has made me more confident in my own convictions from now on.
