I have a valid question, that I'm surprised no one has asked yet. What gives you the right to decide that any coin at all needs to be attacked? It shouldn't matter what your opinion is of any particular coin, there are people who have money tied up in those coins, and you are bragging about having the ability to kill those coins and cause people to lose their money. The fact that you are publicly posting this threat is either incredibly bold, or incredibly stupid.
If however the point you are trying to make is to be some way beneficial to the devs and can be used to strengthen the block chains to prevent attacks like this from happening, then more power to you.
Your first paragraph was my original response. But I read past the first 3 sentences and realized that this is a valid cause. The bad coins should be attacked. This is noble work. It's not done out of malice or a general hatred, but to cull the herd or at least toughen the coins that remain standing after the attacks.
Hopefully the OP will share his findings and we will learn more about PoS crypto. I'm very interested in the results.
