I'm afraid the maths here is incorrect,

60,000 X 100 = 6,000,000

6 Million rather than Billion, still a very nice return from a $48,000 investment if the figures do become a reality.

Ark does have potential to keep rising, its had a fast rise so far, I got on the train at $1 exactly, swapping my NEO which had risen to $40+ at the time for arcs, all in all that paid off very well, as the 40 Arks a NEO are now worth around $150 whereas each NEO is nearer 20.
