Of course it's not legit:
Anything premined with an IPO over the span of 1 second usually has an abysmal market penetration defeating the whole purpose of cryptocurrency, or just results in a pyramid scheme to try and force the masses to enrich a handful of people. This isn't why Bitcoin was created and seems like a blatant hijack of it to turn it into a get rich quick scheme. If the proof of stake coin is mined over a long period, like Bitcoin is, then my stance on that is obviously different.
Even the name is garbage. "Swarmcoin", are you serious?
