Did they save my investment from harm?
YES

Hmmm not really agree with you there, let's take my case, i had quite some k VRC on mintpal, it seems I will have not lost any VRC... BUT it's not only the amount of coins, it's more the value of my coins, a realistic scenario is massive vrc dumps comming in at all other exchanges trading vrc and my coins being worth jackshit at the moment I can access them again on mintpal.

Now, I donot say this is the fault of the VRC team, these guys did an amazing job and I can imagine the decision for rollback was not taken lightly... my first reaction was happiness but then I sat back and tought about it a bit longer and could do nothing but conclude this rollback is the worst solution possible.  It destroys the chain of trust, it removed all realworld value from the coin.
No, I'm certainly not trying to FUD cause I'll lose quite some money in this and I truly hoped VRC would be my intermediate ticket to moon... sadly a ticked destroyed by the amateurism that is mintpal.

I can only do 1 legit sugestion here and that is for everybody to pullback all coins from Mintpal, they destroyed again a good thing and they should get seriously punished for it!
