488k transactions per second? - CREDITS

Today, CREDITS posted an article on their Alpha test - showing 488k transactions per second

• For now, I am going to risk 35-40$ for 100 Credits, and buy some more once they release it to the public and everyone can test it.

If, they really should be a "scam" or incompetent, I'll survive losing the 40$.
