With PoS coin, on the other hand you can potentially sell your "investment" in the coin prior to your attack being discovered by the rest of the network, which would result in you having a zero net cost to an attacker

Who told you that non-sense?

Me.

Or anyone else with an IQ over 100 whom can infer this algorithmic conclusion.

Assume my IQ being 97ish, could you provide a concrete but simple step by step guide?
I would like to try such a zero-cost attack myself.

Thanks in advance.

Go here: https://bitcointalk.org/index.php?board=159.0
Pick one new coin with PoS that hasn't been launched yet. Find the best options to acquire as much as possible of the coins cheaply (mining, IPO, market). In 2-3 months build your own little network corner with 2+ nodes, keep collecting the coins. Monitor the network for active nodes count (there should be pools and exchanges at least). Scale up your network before the attack to have more nodes than the network (even on the same IP). Power down clients, edit peer list, ban seed peers (maybe edit the source to exclude them). Start staking across your nodes and increase your chain's difficulty while separated from the network. DDoS the fair nodes and release your network to most peers (except seed peers maybe). Be sure to read the rules on chain reorgs and stake limits.

[...]

Thanks for elaborating.

For a coin not yet launched the initial financial risk (acquire a lot of coins of a coin with maybe no future value plus building a substantial personal network) seems like a no-go to me. What about an "established" PoS coin? Costs of the way described could be astronomical?!
