All coins can be "questionable" at a given time.. some are better or worse than others, but that's the point of mining new coins. CRYPT has only ever been hype - there's *still* nothing of substance, yet. Maybe they will deliver, maybe they won't, but there's no reason to jump on mining something based on 100% hype unless you're just hoping that somehow leads to a pump (which can be a viable strategy, but isn't the one we use for ipoMiner).
I think you may misunderstand what we try to do at ipoMiner. We aren't in the business of predicting what coin will get hyped and pumped 2 weeks from now. Our goal has always been, and continues to be, to find what coin can you mine now and sell within the next 1-36 hours. Not to toot my own horn, but we are *extremely* good at that - better than any other public site in this business, I would argue.
We do not advise holding the coins we mine for substantial periods of time - that has never been the intent of our coin selection or goal. I think what it sounds like you're looking for is a trading group, which has never been our intended purpose. I know I've said it before, but I'll repeat it here in case anyone hasn't heard it from me before: I specifically encourage everyone to separate mining from trading.
Mine what's profitable to mine; trade what you think is profitable to trade.. but don't use us as your trading advice platform, since that's not what we try to offer
Now, as far as your list of "turkeys" go:
WC and AC were massively profitable to mine - two of the most profitable coins of the year, aside from SpainCoin and BlackCoin, actually. BLU, OC, YC, SHIBE, and DOJE were not smash hits, but they were as profitable or more profitable, to mine and sell, than any other coin that was available at the time they were released.
HOC was a total failure, I 100% agree. It was also mined for what, less than 6-12 hours on the multiport? Hardly a substantial investment, and there were not any stellar alternatives at the time.
We mined LION for less than 30 minutes.
SYNC, FRAC, WEST, MAST, LOL, VOOT, and PIGGY have all been terrific for miners to mine and sell. DRK and HIRO are older coins that users asked us to add as x11 direct ports.
LIMX and KIWI were more profitable to mine and sell than other coins based on immediate profitability, but never did anything particularly exciting/sort of fizzled, that's true.
Most of the "bigger pools" mine EVERY coin out there. We try to select the best ones, from the perspective of mining profitability, using the information that is available around the time of launch and after. Most of the coins you mention were overhyped and have never delivered on their promises - they could have just as easily failed as they could have gone up, and yes, any coin that increases by more than 10x based on pure hype could be called a "lucky pump".
