Not quite.
EByteBall is the first and they aren't so much imitating as they are adding one more crypto to the ecoin craze that has swept BCT lately. And if it wasn't obvious already, the only similarity between either of those two utterly useless tokens and ByteBall is simply the name and nothing more.
Interesting to see that the price has dipped as usual following the airdrop even though it didn't rise much this time.
