Bytecoin didn't cope with such an increase of transactions in their blockchain. It's not a good indicator for a cryptocurrency, showing that they are not ready for such a challenge.
The vulnerability of bytecoin already discovered and that's why binance is blocking any bytecoin deposit. Man, look at another thread and how some people are using this current situation to promoting a new coin that similar to the bytecoin.
I guess people should move to the future coin just like ethereum.
