One of the altcoins I have personally been most excited about ever since it originally launched, is NobleCoin. Not just because their developer is one of the brightest minds we have seen in the altcoin scene so far, but simply because of the sheer amount of services NOBL has to offer, which still go by unnoticed by the general cryptocurrency community.
While the focus for digital currency and altcoins is mostly on marketing and education, as it should be, there is still the human element. Interaction between all parties making up the network cannot be replaced by code, tools or anything else. We need to make cryptocurrency more “human’ than it is right now.
