I don't see good reasons for HEX to be a long term investment. First, its certainly one of those pyramid schemes that you should never want to hold for long term and end up losing. They may be profitable but only for temporary reasons. Other than that, there's no long term utility case that keeps you wanting it, so better stick to bitcoin and established altcoins, they are more stable than HEX. Just keep doing DYOR so you'll never be misled.
