What's even more awesome is that Bitcoin is swallowing this crap without skipping a beat. Their attacks are at most causing short term inconvenience, and the intensity keeps on declining upon each subsequent wave of attacks. This is of course the energy dissipation pattern of a ponzi scheme. Eventually you consume all the suckers and have to suck.
