Update on the potential security issues mentioned earlier.

As a cautionary measure and since MINT does not really need PoW, we have decided to get rid of the PoW. We don't want to take any security risk.
And since our ego is less important than your hard earned money, we won't have any problem to be thankful to another coin dev if it appears he has helped to increase MintCoin's security.

If it appears? What a joke.

Dishonest dev, dishonest community.

Mintcoin Dev Team, wear this as a badge of honour from mr_random! mr_random has shown his hand is as empty as his words. Congrats Dev Team for taking the high road, reacting quickly, and doing what is right!

Looks like the low diff of pow can be explored, but so far I don't see any real successful attacks. No double spending reported, no fake coins generated outside what the dev defined in the code. For pow/pos coins I saw a few had on and off pos blocks (and pow blocks due to the fact that the diff retargets linked the two together). I don't think the attack on delaying pos will do anything. Once pow only, the diff appears going up quickly, and one can not make the pow only coin this way. The pos blocks do not need to be generated at a precise time, it doesn't matter, you have 20 days after it is ready to generate before no more coin-day be accumulated.

I think the dev team did the right thing. In order to prevent any further exploit on the low diff pow, just to remove it. As for pure pos coins, pos itself may have many issues, but so far no successful attack is known on the pos coins.

Blackcoin is stupid enough causing big issues, and killed a great exchange (cryptorush), from what I read, the BC dev said he can not do much with the situation (that led to the death of cryptorush). Now they started exploring pow/pos with low pow diff, trying to attack other coins. So far they did not succeed in anything, just cause some panic among a few people who don't understand the details.
