If that's Bitcoin then this would actually give you, at the current exchange rate of BTC to USD:
0.000000000002557444% USD. If you got that card once every milliscond, you would need 31 years to have 2.5$.
I doubt you'd be rich with one card except lol.
It says you only have ten seconds, I doubt you could log onto another (Unix) computer in that time, open the terninal, run the man oage and then run over and enter a valid command...
