I don't understand why you are all so emotional in this topic. Most of you says they are in for the long run, but then react at every price swing. It seems like you either invested more than you should to react this way, or expected to get a return sooner than a few years.
This is not how a long term investment work. Just put your money in the coin you believe will success, diversify on some other project with also good expected future and then stop following the day to day market.
I only check the price and the news once a month, and that allowed me for example on the ETH to get a 1000% ROI, while it could have only been much lower if i were to follow the daily activities, because of panic sell.
In some case, you will end up with nothing because the coin will be dead, that's to be expected, but the few coins that will success in your investment will cover your loss easily. So stop worrying, stop discussing daily price, and be there really for the long term development of the coin.
