I don't think that it's dying because as I can see there's just a big upscale with BTC and ETH these past few days. Also, you might try to choose different alt coins if you want to earn and not lose earnings. It's just that sometimes in a span of 3 months some coins are going down but if you take a look of a longer time scale you will notice that downscale is just normal for alt coins. Also, just be wise at choosing your prefer alt coins.
