Right... You can use computational power to do this, but it is exponentially cheaper than mining, totally outcompeting those who play the game honestly. If taken to extremes, and everyone starts throwing massive computing power to game the system, then your supposed PoS system turns into PoW indirectly, which kind of defeats the point of PoS in the first place.
Everything is cheaper than ASICS Mining, the N@S Lie states that no addition resources will be required.
Clearly you can see the CPU increased requirement, you are forgetting the Memory Ram Requirements, may increase by the factor of the number of Forks.
All of those will draw more energy. Your Costs will increase for absolutely no reason with No real Increase in Rewards.
Your Reward rate will be the same whether you multistake or not, the block of coins will then deactivate until it reaches minimum stake age.
The Fact is , if you are able to stake on multiple forks, you would have staked on the main fork and added to its difficulty without Negating it by multistaking, and all of the rest of the multistaking nonsense is a waste of time.
The N@S lie has been out for a few years ,
where are the multistaking clients?There are'nt any, because they don't really give you the advantages you think they do.
Just another one of G.Maxwell lies,
The Nothing at Stake Lie
or
The BTC can't increase transaction capacity without segwit Lie
Both are lies, when you look at them closely.
FYI:
If the Nothing at Stake Lie were True ,
Why isn't G.Maxwell crushing Blackcoin, or Diamond or Navcoin, by exploiting the N@S,
the reason is he can't because he lied!
