I'm not 100% sure what coin i'll attack. If people donate I might try for Vertcoin which will be $300-500 to attack. But if I stick with Einsteinium it will be very cheap, maybe $20-40. They could hardfork but I doubt they will. It's also sort of hard to implement a solution that quickly.
Bytecoin would take maybe a thousand, 4 or 5 if we want to get a transaction confirmed in an exchange. I'll do the biggest coin I can I'll put in $50 of my own money If anyone wants to donate you can:
