So yesterday EOS was pumping 50 ETH an hour worth of gas to intentionally attack the ethereum network.
24 hours of continuous attack costed those motherfuckers 700,000$.
Fair price to pay (with crowdfunded money lol) to bash your competitor perhaps.
But what if the price per eth were 45$ instead of 450$?
The attack would have costed just 2200$/hour, at a price like that a wealthy competitor like EOS could easily afford to permaclog the fucking thing for several months dethroning it and getting eventually back the money back once Ethereum is abandoned.
