Dat feeling when you've thrown away tens of thousands of dollars by selling before a 20x gain

Happy for DRK, sad for me. Much conflict.
It doesn't have to be that way. I sold all my DRK twice before re-investing this last time.
Hopefully you made some BTC on the previous run-ups in price and can re-invest on the next correction.
To do that you must have skill or luck. It's better to hold if you have neither.
I agree.
I believe I have both skill and a bit of luck. I sell on the way up. When Darkcoin had earlier run-ups in price I sold all my Darkcoin and made a decent profit. When the price continued to rise later I reinvested.
Yes, if I had held on to my original Darkcoins when I bought -13.9547 BTC worth at 0.0019173 on April 23rd I would be doing great. However, no one can tell when a coin will die and you will be holding the bag.
I sold on the way up for both Blackcoin and Cinni and made a good amount of profit on each of those by doing so and they later never recovered. If a coin does recover like Darkcoin did you can invest at a later price.
