This coin was indeed instamined over 80% and the blockchain is your proof. You can see that over 80% of Bytecoins total coin supply was mined before it became public. AKA a 80%+ premine.
But it seems like such a cool coin and the people on this thread say it was not premined.
How could it have such a high marketcap if it is a scam?
Doesn't the high marketcap mean lots of people are buying it
it is not a scam, people just like to spread FUD. This coins wasn't premined. It just wasn't announced publicly on bitcointalk.org.
If you use there analogy then I could say that bitcoin was premined because I wasn't aware of it until 2 years after it launched.
