What would be the point in hitting 51% all they would do is devalue the coins they own.
You know, that would sorta make sense if the miners had to store their profits in BTC.
Which they do not -- they can sell BTC for USD.
Assuming that miners (who may not be planning to even stay in the mining game once their gear becomes unprofitable) have the same interests as the hodlers ... it doesn't make sense.
