Are we under attack??

No. Bitcoin crashed so some miners switched to more promising currency.

I've asked this before but no one responded if it's an exact copy of bitcoin how is it more promising?

Simple. With less hashpower u get more coins. History of altcoins proved that altcoins often jump to x10-x1000 of initial price.

Wat? So by more promising you mean "there are less hashes so I can get rich as an early adopter"
