I'm not sure whether he is trolling or he truly believes that this can be done. In either case, whoever attempts to do this will be disappointed. However, this could also be a targeted attempt, i.e. they want the individual(s) to hack someone's system which has X amount of BTC. While this technically isn't a hack on the network itself, it is a doable hack.

That's why there's the possibility of a targeted attack as I described above.
