assault – Can the declare that “Bitcoin has a charge mannequin that may be simply manipulated” be confirmed? In that case are there any proposed options?

phillipma1957 claims:

Backside line is the charge setup is topic to assault at little or no price if any main pool will get concerned within the assault.
I’m a small industrial miner perhaps 160kwatts of drugs which is a drop within the bucket.
However when you have 100 megawatts and work with a big pool with a couple of different huge mines you possibly can actually do an entire lot to maneuver charges from 0.15 btc a block final yr to 1.50 btc a block now. I do assume that is taking place now.
However I additionally assume it means we’re about to see a big btc value improve. As this tremendous sized blocks appear to occur at first of bull runs.
