The problem with most POS coins is that they have no intrinsic value.

In Cloak's case there is also inflation with no incentive to secure the network. POS3, if implemented, should go some way to resolving this issue.

At least with POW coins the minimum value of the coins is linked to the energy cost associated with mining them.

I like Cloak but it won't take much effort for a better established, better funded PoW coin to clone Enigma and leave Cloak without a unique value proposition.

I hope this doesn't happen but I feel it is inevitable. Cloak will eventually become a victim of having good technology but being too small and slow to implement.
