Is there any way to add darkcoin functionality to mintcoin eventually? Adding true anonymity would add another perk to this coin.
I just sold all my Darkcoin... One my issues with it is that yes, Darksend when it's finished can just be added to any other coin as an added functionality I believe.
For the main part, Proof-of-Stake and the function of Staking somewhat relinquishes your wallets anonymity onto the blockchain.
Therefore, the addition of effective 'darksend' technology into any PoS coin is much more difficult, certainly in the immediate future. It will be much simpler for developers to include this type of function into non-PoS coins.
In terms of Alt. coins, Mintcoin and Darkcoin are perhaps two of the main and most important coins looking forward, imho.
Mintcoin - a pure PoS 'energy saving' coin that serves as an interest bearing / savings account.
Darkcoin - an energy efficient PoW algorithm and true 'anonymous' transactions, when Darksend is fully implemented.
