I am a senior member in this bitcointalk forum, but I want to remain anonymous.
I noticed Vericoin discussion when go to Altcoin ANN, and here is some of my insight:

First, a few questions:

1. Did mintpal really lost Vericoin, because of being hacked?
After reading their official announcement, the information is rather vague. Is there a possibility that coins are withdrawn by some big bagholders? Is there possibility that coins are sold by Mintpal (or its personnel) to other people and then they want to reverse the transaction while not paying the money back?

2. Vericoin was hacked, while other coins, including Bitcoin, was intact. Is it because the problem of Vericoin blockchain, or because of the safety hazard in Mintpal?

3. Vericoin group decided to roll-back the blockchain, is this a result after a deliberate consideration, or not?

4. If a small Altcoin-Bitcoin exchange site get compromised, will the Vericoin team do the same thing to roll back?

Then a few insights:

Cryptocurrency is created to be de-centralized. By reversing some transactions through the intervention of development team, it goes against its initial objective.

Cryptocurrency is created to be not regulated by authorities, such as countries. What happened to Vericoin today goes against this objective, because it is controlled by an exchange site. Suppose someday a country authority send request to the Vericoin development team about some Vericoin is held by some bad guys and the authority request a hard fork to remove those Vericoins, or send those coins to the country authority, based on what happened, I doubt the team will say no.
